The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-414532 advisory.

    An unprivileged write to the file handler flaw in the Linux kernel's control groups and namespaces     subsystem was found in the way users have access to some less privileged process that are controlled by     cgroups and have higher privileged parent process. It is actually both for cgroup2 and cgroup1 versions of     control groups. A local user could use this flaw to crash the system or escalate their privileges on the     system.

Tenable has extracted the preceding description block directly from the Unity Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The version of kernel installed on the remote host is prior to 5.4.181-99.354. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.4-2022-023 advisory.

The remote SUSE Linux SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:0371-1 advisory.

  - The BPF subsystem in the Linux kernel before 4.17 mishandles situations with a long jump over an     instruction sequence where inner instructions require substantial expansions into multiple BPF     instructions, leading to an overflow. This affects kernel/bpf/core.c and net/core/filter.c.
    (CVE-2018-25020)

  - An issue was discovered on Broadcom Wi-Fi client devices. Specifically timed and handcrafted traffic can     cause internal errors (related to state transitions) in a WLAN device that lead to improper layer 2 Wi-Fi     encryption with a consequent possibility of information disclosure over the air for a discrete set of     traffic, a different vulnerability than CVE-2019-9500, CVE-2019-9501, CVE-2019-9502, and CVE-2019-9503.
    (CVE-2019-15126)

  - A vulnerability was found in Linux kernel, where a use-after-frees in nouveau's postclose() handler could     happen if removing device (that is not common to remove video card physically without power-off, but same     happens if unbind the driver). (CVE-2020-27820)

  - In unix_scm_to_skb of af_unix.c, there is a possible use after free bug due to a race condition. This     could lead to local escalation of privilege with System execution privileges needed.

  - Rogue backends can cause DoS of guests via high frequency events T[his CNA information record relates to     multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Xen offers the     ability to run PV backends in regular unprivileged guests, typically referred to as driver domains.
    Running PV backends in driver domains has one primary security advantage: if a driver domain gets     compromised, it doesn't have the privileges to take over the system. However, a malicious driver domain     could try to attack other guests via sending events at a high frequency leading to a Denial of Service in     the guest due to trying to service interrupts for elongated amounts of time. There are three affected     backends: * blkfront patch 1, CVE-2021-28711 * netfront patch 2, CVE-2021-28712 * hvc_xen (console) patch     3, CVE-2021-28713 (CVE-2021-28711, CVE-2021-28712, CVE-2021-28713)

  - Guest can force Linux netback driver to hog large amounts of kernel memory T[his CNA information record     relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.]     Incoming data packets for a guest in the Linux kernel's netback driver are buffered until the guest is     ready to process them. There are some measures taken for avoiding to pile up too much data, but those can     be bypassed by the guest: There is a timeout how long the client side of an interface can stop consuming     new packets before it is assumed to have stalled, but this timeout is rather long (60 seconds by default).
    Using a UDP connection on a fast interface can easily accumulate gigabytes of data in that time.
    (CVE-2021-28715) The timeout could even never trigger if the guest manages to have only one free slot in     its RX queue ring page and the next package would require more than one free slot, which may be the case     when using GSO, XDP, or software hashing.

A local user could use this flaw to get unauthorized access to some data. (CVE-2021-4002)

  - A read-after-free memory flaw was found in the Linux kernel's garbage collection for Unix domain socket     file handlers in the way users call close() and fget() simultaneously and can potentially trigger a race     condition. This flaw allows a local user to crash the system or escalate their privileges on the system.
    This flaw affects Linux kernel versions prior to 5.16-rc4. (CVE-2021-4083)

  - A vulnerability was found in btrfs_alloc_tree_b in fs/btrfs/extent-tree.c in the Linux kernel due to an     improper lock operation in btrfs. In this flaw, a user with a local privilege may cause a denial of     service (DOS) due to a deadlock problem. (CVE-2021-4149)

  - An unprivileged write to the file handler flaw in the Linux kernel's control groups and namespaces     subsystem was found in the way users have access to some less privileged process that are controlled by     cgroups and have higher privileged parent process. It is actually both for cgroup2 and cgroup1 versions of     control groups. A local user could use this flaw to crash the system or escalate their privileges on the     system. (CVE-2021-4197)

  - A use-after-free flaw was found in nci_request in net/nfc/nci/core.c in NFC Controller Interface (NCI) in     the Linux kernel. This flaw could allow a local attacker with user privileges to cause a data race problem     while the device is getting removed, leading to a privilege escalation problem. (CVE-2021-4202)

  - In the Linux kernel through 5.15.2, hw_atl_utils_fw_rpc_wait in     drivers/net/ethernet/aquantia/atlantic/hw_atl/hw_atl_utils.c allows an attacker (who can introduce a     crafted device) to trigger an out-of-bounds write via a crafted length value. (CVE-2021-43975)

  - In the Linux kernel through 5.15.2, mwifiex_usb_recv in drivers/net/wireless/marvell/mwifiex/usb.c allows     an attacker (who can connect a crafted USB device) to cause a denial of service (skb_over_panic).
    (CVE-2021-43976)

  - A use-after-free exists in drivers/tee/tee_shm.c in the TEE subsystem in the Linux kernel through 5.15.11.

  - A flaw was found in the sctp_make_strreset_req function in net/sctp/sm_make_chunk.c in the SCTP network     protocol in the Linux kernel with a local user privilege access. In this flaw, an attempt to use more     buffer than is allocated triggers a BUG_ON issue, leading to a denial of service (DOS). (CVE-2022-0322)

  - A random memory access flaw was found in the Linux kernel's GPU i915 kernel driver functionality in the     way a user may run malicious code on the GPU. This flaw allows a local user to crash the system or     escalate their privileges on the system. (CVE-2022-0330)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - An unprivileged write to the file handler flaw in the Linux kernel's control groups and namespaces     subsystem was found in the way users have access to some less privileged process that are controlled by     cgroups and have higher privileged parent process.

    AMD recommends using a software mitigation for this issue, which the kernel is enabling by default. The     Linux kernel will use the generic retpoline software mitigation, instead of the specialized AMD one, on     AMD instances (*5a*). This is done by default, and no administrator action is needed. (CVE-2021-26401)

    An unprivileged write to the file handler flaw in the Linux kernel's control groups and namespaces     subsystem was found in the way users have access to some less privileged process that are controlled by     cgroups and have higher privileged parent process. It is actually both for cgroup2 and cgroup1 versions of     control groups. A local user could use this flaw to crash the system or escalate their privileges on the     system. (CVE-2021-4197)

The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2022:1975 advisory.

  - An out-of-bounds memory write flaw was found in the Linux kernel's joystick devices subsystem in versions     before 5.9-rc1, in the way the user calls ioctl JSIOCSBTNMAP. This flaw allows a local user to crash the     system or possibly escalate their privileges on the system. The highest threat from this vulnerability is     to confidentiality, integrity, as well as system availability. (CVE-2021-3612)

  - A use-after-free flaw was found in the Linux kernel's Bluetooth subsystem in the way user calls connect to     the socket and disconnect simultaneously due to a race condition. This flaw allows a user to crash the     system or escalate their privileges. The highest threat from this vulnerability is to confidentiality,     integrity, as well as system availability. (CVE-2021-3752)

  - A flaw was found in the Linux SCTP stack. A blind attacker may be able to kill an existing SCTP     association through invalid chunks if the attacker knows the IP-addresses and port numbers being used and     the attacker can send packets with spoofed IP addresses. (CVE-2021-3772)

  - A flaw in netfilter could allow a network-connected attacker to infer openvpn connection endpoint     information for further use in traditional network attacks. (CVE-2021-3773)

  - A memory leak flaw in the Linux kernel's hugetlbfs memory usage was found in the way the user maps some     regions of memory twice using shmget() which are aligned to PUD alignment with the fault of some of the     memory pages. A local user could use this flaw to get unauthorized access to some data. (CVE-2021-4002)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - Wi-Fi Protected Access (WPA and WPA2) allows reinstallation of the Group Temporal Key (GTK) during the     group key handshake, allowing an attacker within radio range to replay frames from access points to     clients. (CVE-2017-13080)

  - It was found that cephx authentication protocol did not verify ceph clients correctly and was vulnerable     to replay attack. Any attacker having access to ceph cluster network who is able to sniff packets on     network can use this vulnerability to authenticate with ceph service and perform actions allowed by ceph     service. Ceph branches master, mimic, luminous and jewel are believed to be vulnerable. (CVE-2018-1128)

  - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent     Privacy (WEP) doesn't require that received fragments be cleared from memory after (re)connecting to a     network. Under the right circumstances, when another device sends fragmented frames encrypted using WEP,     CCMP, or GCMP, this can be abused to inject arbitrary network packets and/or exfiltrate user data.
    (CVE-2020-24586)

  - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent     Privacy (WEP) doesn't require that all fragments of a frame are encrypted under the same key. An adversary     can abuse this to decrypt selected fragments when another device sends fragmented frames and the WEP,     CCMP, or GCMP encryption key is periodically renewed. (CVE-2020-24587)

  - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent     Privacy (WEP) doesn't require that the A-MSDU flag in the plaintext QoS header field is authenticated.
    Against devices that support receiving non-SSP A-MSDU frames (which is mandatory as part of 802.11n), an     adversary can abuse this to inject arbitrary network packets. (CVE-2020-24588)

  - An issue was discovered in the kernel in NetBSD 7.1. An Access Point (AP) forwards EAPOL frames to other     clients even though the sender has not yet successfully authenticated to the AP. This might be abused in     projected Wi-Fi networks to launch denial-of-service attacks against connected clients and makes it easier     to exploit other vulnerabilities in connected clients. (CVE-2020-26139)

  - An issue was discovered in the ALFA Windows 10 driver 6.1316.1209 for AWUS036H. The WEP, WPA, WPA2, and     WPA3 implementations accept plaintext frames in a protected Wi-Fi network. An adversary can abuse this to     inject arbitrary data frames independent of the network configuration. (CVE-2020-26140)

  - An issue was discovered in the ALFA Windows 10 driver 6.1316.1209 for AWUS036H. The Wi-Fi implementation     does not verify the Message Integrity Check (authenticity) of fragmented TKIP frames. An adversary can     abuse this to inject and possibly decrypt packets in WPA or WPA2 networks that support the TKIP data-     confidentiality protocol. (CVE-2020-26141)

  - An issue was discovered in the kernel in OpenBSD 6.6. The WEP, WPA, WPA2, and WPA3 implementations treat     fragmented frames as full frames. An adversary can abuse this to inject arbitrary network packets,     independent of the network configuration. (CVE-2020-26142)

  - An issue was discovered in the ALFA Windows 10 driver 1030.36.604 for AWUS036ACH. The WEP, WPA, WPA2, and     WPA3 implementations accept fragmented plaintext frames in a protected Wi-Fi network. An adversary can     abuse this to inject arbitrary data frames independent of the network configuration. (CVE-2020-26143)

  - An issue was discovered on Samsung Galaxy S3 i9305 4.4.4 devices. The WEP, WPA, WPA2, and WPA3     implementations accept plaintext A-MSDU frames as long as the first 8 bytes correspond to a valid RFC1042     (i.e., LLC/SNAP) header for EAPOL. An adversary can abuse this to inject arbitrary network packets     independent of the network configuration. (CVE-2020-26144)

  - An issue was discovered on Samsung Galaxy S3 i9305 4.4.4 devices. The WEP, WPA, WPA2, and WPA3     implementations accept second (or subsequent) broadcast fragments even when sent in plaintext and process     them as full unfragmented frames. An adversary can abuse this to inject arbitrary network packets     independent of the network configuration. (CVE-2020-26145)

  - An issue was discovered on Samsung Galaxy S3 i9305 4.4.4 devices. The WPA, WPA2, and WPA3 implementations     reassemble fragments with non-consecutive packet numbers. An adversary can abuse this to exfiltrate     selected fragments. This vulnerability is exploitable when another device sends fragmented frames and the     WEP, CCMP, or GCMP data-confidentiality protocol is used. Note that WEP is vulnerable to this attack by     design. (CVE-2020-26146)

  - An issue was discovered in the Linux kernel 5.8.9. The WEP, WPA, WPA2, and WPA3 implementations reassemble     fragments even though some of them were sent in plaintext. This vulnerability can be abused to inject     packets and/or exfiltrate selected fragments when another device sends fragmented frames and the WEP,     CCMP, or GCMP data-confidentiality protocol is used. (CVE-2020-26147)

  - A flaw was found in the Linux kernel's implementation of MIDI, where an attacker with a local account and     the permissions to issue ioctl commands to midi devices could trigger a use-after-free issue. A write to     this specific memory while freed and before use causes the flow of execution to change and possibly allow     for memory corruption or privilege escalation. The highest threat from this vulnerability is to     confidentiality, integrity, as well as system availability. (CVE-2020-27786)

  - In unix_scm_to_skb of af_unix.c, there is a possible use after free bug due to a race condition. This     could lead to local escalation of privilege with System execution privileges needed. User interaction is     not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-196926917References:
    Upstream kernel (CVE-2021-0920)

  - A race condition accessing file object in the Linux kernel OverlayFS subsystem was found in the way users     do rename in specific way with OverlayFS. A local user could use this flaw to crash the system.
    (CVE-2021-20321)

  - An information disclosure vulnerability exists in the ARM SIGPAGE functionality of Linux Kernel v5.4.66     and v5.4.54. The latest version (5.11-rc4) seems to still be vulnerable. A userland application can read     the contents of the sigpage, which can leak kernel memory contents. An attacker can read a process's     memory at a specific offset to trigger this vulnerability. This was fixed in kernel releases: 4.14.222     4.19.177 5.4.99 5.10.17 5.11 (CVE-2021-21781)

  - An issue was discovered in the Linux kernel before 5.11.3 when a webcam device exists. video_usercopy in     drivers/media/v4l2-core/v4l2-ioctl.c has a memory leak for large arguments, aka CID-fb18802a338b.
    (CVE-2021-30002)

  - Improper input validation in the Intel(R) Ethernet ixgbe driver for Linux before version 3.17.3 may allow     an authenticated user to potentially enable denial of service via local access. (CVE-2021-33098)

  - A vulnerability was found in the Linux kernel in versions prior to v5.14-rc1. Missing size validations on     inbound SCTP packets may allow the kernel to read uninitialized memory. (CVE-2021-3655)

  - A lack of CPU resource in the Linux kernel tracing module functionality in versions prior to 5.14-rc3 was     found in the way user uses trace ring buffer in a specific way. Only privileged local users (with     CAP_SYS_ADMIN capability) could use this flaw to starve the resources causing denial of service.
    (CVE-2021-3679)

  - hso_free_net_device in drivers/net/usb/hso.c in the Linux kernel through 5.13.4 calls unregister_netdev     without checking for the NETREG_REGISTERED state, leading to a use-after-free and a double free.
    (CVE-2021-37159)

  - A use-after-free flaw was found in the Linux kernel's Bluetooth subsystem in the way user calls connect to     the socket and disconnect simultaneously due to a race condition. This flaw allows a user to crash the     system or escalate their privileges. The highest threat from this vulnerability is to confidentiality,     integrity, as well as system availability. (CVE-2021-3752)

  - A flaw was found in the Linux SCTP stack. A blind attacker may be able to kill an existing SCTP     association through invalid chunks if the attacker knows the IP-addresses and port numbers being used and     the attacker can send packets with spoofed IP addresses. (CVE-2021-3772)

  - ** DISPUTED ** In drivers/char/virtio_console.c in the Linux kernel before 5.13.4, data corruption or loss     can be triggered by an untrusted device that supplies a buf->len value exceeding the buffer size. NOTE:
    the vendor indicates that the cited data corruption is not a vulnerability in any existing use case; the     length validation was added solely for robustness in the face of anomalous host OS behavior.
    (CVE-2021-38160)

  - net/netfilter/nf_conntrack_standalone.c in the Linux kernel before 5.12.2 allows observation of changes in     any net namespace because these changes are leaked into all other net namespaces. This is related to the     NF_SYSCTL_CT_MAX, NF_SYSCTL_CT_EXPECT_MAX, and NF_SYSCTL_CT_BUCKETS sysctls. (CVE-2021-38209)

  - A memory leak flaw in the Linux kernel's hugetlbfs memory usage was found in the way the user maps some     regions of memory twice using shmget() which are aligned to PUD alignment with the fault of some of the     memory pages. A local user could use this flaw to get unauthorized access to some data. (CVE-2021-4002)

  - A read-after-free memory flaw was found in the Linux kernel's garbage collection for Unix domain socket     file handlers in the way users call close() and fget() simultaneously and can potentially trigger a race     condition. This flaw allows a local user to crash the system or escalate their privileges on the system.
    This flaw affects Linux kernel versions prior to 5.16-rc4. (CVE-2021-4083)

  - A vulnerability was found in btrfs_alloc_tree_b in fs/btrfs/extent-tree.c in the Linux kernel due to an     improper lock operation in btrfs. In this flaw, a user with a local privilege may cause a denial of     service (DOS) due to a deadlock problem. (CVE-2021-4149)

  - An out of memory bounds write flaw (1 or 2 bytes of memory) in the Linux kernel NFS subsystem was found in     the way users use mirroring (replication of files with NFS). A user, having access to the NFS mount, could     potentially use this flaw to crash the system or escalate privileges on the system. (CVE-2021-4157)

  - An unprivileged write to the file handler flaw in the Linux kernel's control groups and namespaces     subsystem was found in the way users have access to some less privileged process that are controlled by     cgroups and have higher privileged parent process. It is actually both for cgroup2 and cgroup1 versions of     control groups. A local user could use this flaw to crash the system or escalate their privileges on the     system. (CVE-2021-4197)

  - In the Linux kernel through 5.15.2, mwifiex_usb_recv in drivers/net/wireless/marvell/mwifiex/usb.c allows     an attacker (who can connect a crafted USB device) to cause a denial of service (skb_over_panic).
    (CVE-2021-43976)

  - In gc_data_segment in fs/f2fs/gc.c in the Linux kernel before 5.16.3, special files are not considered,     leading to a move_data_page NULL pointer dereference. (CVE-2021-44879)

  - In __f2fs_setxattr in fs/f2fs/xattr.c in the Linux kernel through 5.15.11, there is an out-of-bounds     memory access when an inode has an invalid last xattr entry. (CVE-2021-45469)

  - In the IPv6 implementation in the Linux kernel before 5.13.3, net/ipv6/output_core.c has an information     leak because of certain use of a hash table which, although big, doesn't properly consider that IPv6-based     attackers can typically choose among many IPv6 source addresses. (CVE-2021-45485)

  - In the IPv4 implementation in the Linux kernel before 5.12.4, net/ipv4/route.c has an information leak     because the hash table is very small. (CVE-2021-45486)

  - A vulnerability was found in the Linux kernel's cgroup_release_agent_write in the     kernel/cgroup/cgroup-v1.c function. This flaw, under certain circumstances, allows the use of the cgroups     v1 release_agent feature to escalate privileges and bypass the namespace isolation unexpectedly.
    (CVE-2022-0492)

  - A flaw null pointer dereference in the Linux kernel UDF file system functionality was found in the way     user triggers udf_file_write_iter function for the malicious UDF image. A local user could use this flaw     to crash the system. Actual from Linux kernel 4.2-rc1 till 5.17-rc2. (CVE-2022-0617)

  - A use-after-free flaw was found in the Linux kernel's FUSE filesystem in the way a user triggers write().
    This flaw allows a local user to gain unauthorized access to data from the FUSE filesystem, resulting in     privilege escalation. (CVE-2022-1011)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote CentOS Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the kernel-5.14.0-347.el9 build changelog.

  - A stack overflow flaw was found in the Linux kernel's TIPC protocol functionality in the way a user sends     a packet with malicious content where the number of domain member nodes is higher than the 64 allowed.
    This flaw allows a remote user to crash the system or possibly escalate their privileges if they have     access to the TIPC network. (CVE-2022-0435)

  - An issue was discovered in net/tipc/crypto.c in the Linux kernel before 5.14.16. The Transparent Inter-     Process Communication (TIPC) functionality allows remote attackers to exploit insufficient validation of     user-supplied sizes for the MSG_CRYPTO message type. (CVE-2021-43267)

  - A vulnerability was found in Linux kernel, where a use-after-frees in nouveau's postclose() handler could     happen if removing device (that is not common to remove video card physically without power-off, but same     happens if unbind the driver). (CVE-2020-27820)

  - An issue was discovered in the Linux kernel through 5.16.11. The mixed IPID assignment method with the     hash-based IPID assignment policy allows an off-path attacker to inject data into a victim's TCP session     or terminate that session. (CVE-2020-36516)

  - A flaw in the processing of received ICMP errors (ICMP fragment needed and ICMP redirect) in the Linux     kernel functionality was found to allow the ability to quickly scan open UDP ports. This flaw allows an     off-path remote user to effectively bypass the source port UDP randomization. The highest threat from this     vulnerability is to confidentiality and possibly integrity, because software that relies on UDP source     port randomization are indirectly affected as well. (CVE-2021-20322)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
