The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2024:3462 advisory.

    The kernel packages contain the Linux kernel, the core of any Linux operating system.

    Security Fix(es):

    * RHEL: Add Spectre-BHB mitigation for AmpereOne (CVE-2023-3006)

    * kernel: net:emac/emac-mac: Fix a use after free in emac_mac_tx_buf_send (CVE-2021-47013)

    * kernel: net: bridge: data races indata-races in br_handle_frame_finish() (CVE-2023-52578)

    Bug Fix(es):

    * XFS: thaw operation hungs if caches are dropped while FS is frozen  (JIRA:RHEL-34522)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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 Virtualization installation on the remote host is affected by the following vulnerabilities :

  - An issue was discovered in the Linux kernel through 6.0.9. drivers/media/dvb-core/dvb_net.c has a     .disconnect versus dvb_device_open race condition that leads to a use-after-free. (CVE-2022-45886)

  - A hash collision flaw was found in the IPv6 connection lookup table in the Linux kernel's IPv6     functionality when a user makes a new kind of SYN flood attack. A user located in the local network or     with a high bandwidth connection can increase the CPU usage of the server that accepts IPV6 connections up     to 95%. (CVE-2023-1206)

  - In multiple functions of binder.c, there is a possible memory corruption due to a use after free. This     could lead to local escalation of privilege with no additional execution privileges needed. User     interaction is not needed for exploitation. (CVE-2023-21255)

  - A known cache speculation vulnerability, known as Branch History Injection (BHI) or Spectre-BHB, becomes     actual again for the new hw AmpereOne. Spectre-BHB is similar to Spectre v2, except that malicious code     uses the shared branch history (stored in the CPU Branch History Buffer, or BHB) to influence mispredicted     branches within the victim's hardware context. Once that occurs, speculation caused by the mispredicted     branches can cause cache allocation. This issue leads to obtaining information that should not be     accessible. (CVE-2023-3006)

  - An issue was discovered in the Linux kernel through 6.1-rc8. dpu_crtc_atomic_check in     drivers/gpu/drm/msm/disp/dpu1/dpu_crtc.c lacks check of the return value of kzalloc() and will cause the     NULL Pointer Dereference. (CVE-2023-3220)

  - A null pointer dereference flaw was found in the Linux kernel's DECnet networking protocol. This issue     could allow a remote user to crash the system. (CVE-2023-3338)

  - A null pointer dereference was found in the Linux kernel's Integrated Sensor Hub (ISH) driver. This issue     could allow a local user to crash the system. (CVE-2023-3358)

  - A use-after-free vulnerability was found in the Linux kernel's netfilter subsystem in     net/netfilter/nf_tables_api.c. Mishandled error handling with NFT_MSG_NEWRULE makes it possible to use a     dangling pointer in the same transaction causing a use-after-free vulnerability. This flaw allows a local     attacker with user access to cause a privilege escalation issue. We recommend upgrading past commit     1240eb93f0616b21c675416516ff3d74798fdc97. (CVE-2023-3390)

  - The fix for XSA-423 added logic to Linux'es netback driver to deal with a frontend splitting a packet in a     way such that not all of the headers would come in one piece. Unfortunately the logic introduced there     didn't account for the extreme case of the entire packet being split into as many pieces as permitted by     the protocol, yet still being smaller than the area that's specially dealt with to keep all (possible)     headers together. Such an unusual packet would therefore trigger a buffer overrun in the driver.
    (CVE-2023-34319)

  - Linux Kernel nftables Out-Of-Bounds Read/Write Vulnerability; nft_byteorder poorly handled vm register     contents when CAP_NET_ADMIN is in any user or network namespace (CVE-2023-35001)

  - An issue was discovered in the Linux kernel before 6.3.2. A use-after-free was found in     renesas_usb3_remove in drivers/usb/gadget/udc/renesas_usb3.c. (CVE-2023-35828)

  - A use-after-free vulnerability in the Linux kernel's net/sched: cls_u32 component can be exploited to     achieve local privilege escalation. If tcf_change_indev() fails, u32_set_parms() will immediately return     an error after incrementing or decrementing the reference counter in tcf_bind_filter(). If an attacker can     control the reference counter and set it to zero, they can cause the reference to be freed, leading to a     use-after-free vulnerability. We recommend upgrading past commit 04c55383fa5689357bcdd2c8036725a55ed632bc.
    (CVE-2023-3609)

  - An out-of-bounds write vulnerability in the Linux kernel's net/sched: sch_qfq component can be exploited     to achieve local privilege escalation. The qfq_change_agg() function in net/sched/sch_qfq.c allows an out-     of-bounds write because lmax is updated according to packet sizes without bounds checks. We recommend     upgrading past commit 3e337087c3b5805fe0b8a46ba622a962880b5d64. (CVE-2023-3611)

  - A flaw was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem). This issue     may allow a malicious user with CAP_NET_ADMIN privileges to directly dereference a NULL pointer in     xfrm_update_ae_params(), leading to a possible kernel crash and denial of service. (CVE-2023-3772)

  - A use-after-free vulnerability in the Linux kernel's net/sched: cls_fw component can be exploited to     achieve local privilege escalation. If tcf_change_indev() fails, fw_set_parms() will immediately return an     error after incrementing or decrementing the reference counter in tcf_bind_filter(). If an attacker can     control the reference counter and set it to zero, they can cause the reference to be freed, leading to a     use-after-free vulnerability. We recommend upgrading past commit 0323bce598eea038714f941ce2b22541c46d488f.
    (CVE-2023-3776)

  - A use-after-free flaw was found in nfc_llcp_find_local in net/nfc/llcp_core.c in NFC in the Linux kernel.
    This flaw allows a local user with special privileges to impact a kernel information leak issue.
    (CVE-2023-3863)

  - A use-after-free vulnerability was found in the siano smsusb module in the Linux kernel. The bug occurs     during device initialization when the siano device is plugged in. This flaw allows a local user to crash     the system, causing a denial of service condition. (CVE-2023-4132)

  - A flaw was found in the Linux kernel's TUN/TAP functionality. This issue could allow a local user to     bypass network filters and gain unauthorized access to some resources. The original patches fixing     CVE-2023-1076 are incorrect or incomplete. The problem is that the following upstream commits -     a096ccca6e50 ('tun: tun_chr_open(): correctly initialize socket uid'), - 66b2c338adce ('tap: tap_open():
    correctly initialize socket uid'), pass 'inode->i_uid' to sock_init_data_uid() as the last parameter and     that turns out to not be accurate. (CVE-2023-4194)

  - A NULL pointer dereference flaw was found in dbFree in fs/jfs/jfs_dmap.c in the journaling file system     (JFS) in the Linux Kernel. This issue may allow a local attacker to crash the system due to a missing     sanity check. (CVE-2023-4385)

  - A use-after-free flaw was found in vmxnet3_rq_alloc_rx_buf in drivers/net/vmxnet3/vmxnet3_drv.c in     VMware's vmxnet3 ethernet NIC driver in the Linux Kernel. This issue could allow a local attacker to crash     the system due to a double-free while cleaning up vmxnet3_rq_cleanup_all, which could also lead to a     kernel information leak problem. (CVE-2023-4387)

  - A NULL pointer dereference flaw was found in vmxnet3_rq_cleanup in drivers/net/vmxnet3/vmxnet3_drv.c in     the networking sub-component in vmxnet3 in the Linux Kernel. This issue may allow a local attacker with     normal user privilege to cause a denial of service due to a missing sanity check during cleanup.

    Lucas Leong discovered that the Netlink Transformation (XFRM) subsystem in the Linux kernel did not     properly handle state filters, leading to an out- of-bounds read vulnerability. A privileged local     attacker could use this to cause a denial of service (system crash) or possibly expose sensitive     information. (CVE-2023-39194)

    Kyle Zeng discovered that the IPv4 implementation in the Linux kernel did not properly handle socket     buffers (skb) when performing IP routing in certain circumstances, leading to a null pointer dereference     vulnerability. A privileged attacker could use this to cause a denial of service (system crash).
    (CVE-2023-42754)

    Alon Zahavi discovered that the NVMe-oF/TCP subsystem in the Linux kernel did not properly handle queue     initialization failures in certain situations, leading to a use-after-free vulnerability. A remote     attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.
    (CVE-2023-5178)

    Budimir Markovic discovered that the perf subsystem in the Linux kernel did not properly handle event     groups, leading to an out-of-bounds write vulnerability. A local attacker could use this to cause a denial     of service (system crash) or possibly execute arbitrary code. (CVE-2023-5717)

    It was discovered that the TLS subsystem in the Linux kernel did not properly perform cryptographic     operations in some situations, leading to a null pointer dereference vulnerability. A local attacker could     use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-6176)

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

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

The remote SUSE Linux SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:2500-1 advisory.

  - A flaw was found in the Linux kernel Traffic Control (TC) subsystem. Using a specific networking     configuration (redirecting egress packets to ingress using TC action mirred) a local unprivileged user     could trigger a CPU soft lockup (ABBA deadlock) when the transport protocol in use (TCP or SCTP) does a     retransmission, resulting in a denial of service condition. (CVE-2022-4269)

  - An issue was discovered in the Linux kernel through 6.0.9. drivers/media/dvb-core/dvbdev.c has a use-     after-free, related to dvb_register_device dynamically allocating fops. (CVE-2022-45884)

  - An issue was discovered in the Linux kernel through 6.0.10. In drivers/media/dvb-core/dvb_ca_en50221.c, a     use-after-free can occur is there is a disconnect after an open, because of the lack of a wait_event.
    (CVE-2022-45919)

  - A flaw was found in the Linux kernel. A use-after-free may be triggered in asus_kbd_backlight_set when     plugging/disconnecting in a malicious USB device, which advertises itself as an Asus device. Similarly to     the previous known CVE-2023-25012, but in asus devices, the work_struct may be scheduled by the LED     controller while the device is disconnecting, triggering a use-after-free on the struct asus_kbd_leds *led     structure. A malicious USB device may exploit the issue to cause memory corruption with controlled data.
    (CVE-2023-1079)

  - A slab-out-of-bound read problem was found in brcmf_get_assoc_ies in     drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c in the Linux Kernel. This issue could occur     when assoc_info->req_len data is bigger than the size of the buffer, defined as WL_EXTRA_BUF_MAX, leading     to a denial of service. (CVE-2023-1380)

  - A data race flaw was found in the Linux kernel, between where con is allocated and con->sock is set. This     issue leads to a NULL pointer dereference when accessing con->sock->sk in net/tipc/topsrv.c in the tipc     protocol in the Linux kernel. (CVE-2023-1382)

  - A vulnerability was found in the HCI sockets implementation due to a missing capability check in     net/bluetooth/hci_sock.c in the Linux Kernel. This flaw allows an attacker to unauthorized execution of     management commands, compromising the confidentiality, integrity, and availability of Bluetooth     communication. (CVE-2023-2002)

  - An out-of-bounds memory access flaw was found in the Linux kernel's XFS file system in how a user restores     an XFS image after failure (with a dirty log journal). This flaw allows a local user to crash or     potentially escalate their privileges on the system. (CVE-2023-2124)

  - A flaw was found in the networking subsystem of the Linux kernel within the handling of the RPL protocol.
    This issue results from the lack of proper handling of user-supplied data, which can lead to an assertion     failure. This may allow an unauthenticated remote attacker to create a denial of service condition on the     system. (CVE-2023-2156)

  - A use-after-free vulnerability was found in iscsi_sw_tcp_session_create in drivers/scsi/iscsi_tcp.c in     SCSI sub-component in the Linux Kernel. In this flaw an attacker could leak kernel internal information.
    (CVE-2023-2162)

  - A denial of service problem was found, due to a possible recursive locking scenario, resulting in a     deadlock in table_clear in drivers/md/dm-ioctl.c in the Linux Kernel Device Mapper-Multipathing sub-     component. (CVE-2023-2269)

  - A use-after-free vulnerability was found in the Linux kernel's ext4 filesystem in the way it handled the     extra inode size for extended attributes. This flaw could allow a privileged local user to cause a system     crash or other undefined behaviors. (CVE-2023-2513)

  - Improper restriction of operations within the bounds of a memory buffer in some Intel(R) i915 Graphics     drivers for linux before kernel version 6.2.10 may allow an authenticated user to potentially enable     escalation of privilege via local access. (CVE-2023-28410)

  - A known cache speculation vulnerability, known as Branch History Injection (BHI) or Spectre-BHB, becomes     actual again for the new hw AmpereOne. Spectre-BHB is similar to Spectre v2, except that malicious code     uses the shared branch history (stored in the CPU Branch History Buffer, or BHB) to influence mispredicted     branches within the victim's hardware context. Once that occurs, speculation caused by the mispredicted     branches can cause cache allocation. This issue leads to obtaining information that should not be     accessible. (CVE-2023-3006)

  - An issue was discovered in arch/x86/kvm/vmx/nested.c in the Linux kernel before 6.2.8. nVMX on x86_64     lacks consistency checks for CR0 and CR4. (CVE-2023-30456)

  - An issue was discovered in drivers/media/dvb-core/dvb_frontend.c in the Linux kernel 6.2. There is a     blocking operation when a task is in !TASK_RUNNING. In dvb_frontend_get_event, wait_event_interruptible is     called; the condition is dvb_frontend_test_event(fepriv,events). In dvb_frontend_test_event,     down(&fepriv->sem) is called. However, wait_event_interruptible would put the process to sleep, and     down(&fepriv->sem) may block the process. (CVE-2023-31084)

  - qfq_change_class in net/sched/sch_qfq.c in the Linux kernel before 6.2.13 allows an out-of-bounds write     because lmax can exceed QFQ_MIN_LMAX. (CVE-2023-31436)

  - In the Linux kernel through 6.3.1, a use-after-free in Netfilter nf_tables when processing batch requests     can be abused to perform arbitrary read and write operations on kernel memory. Unprivileged local users     can obtain root privileges. This occurs because anonymous sets are mishandled. (CVE-2023-32233)

  - An issue was discovered in the Linux kernel before 6.2.9. A use-after-free was found in bq24190_remove in     drivers/power/supply/bq24190_charger.c. It could allow a local attacker to crash the system due to a race     condition. (CVE-2023-33288)

The remote Ubuntu 16.04 LTS / 18.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6701-2 advisory.

    Ruihan Li discovered that the bluetooth subsystem in the Linux kernel did not properly perform permissions     checks when handling HCI sockets. A physically proximate attacker could use this to cause a denial of     service (bluetooth communication). (CVE-2023-2002)

    It was discovered that the NVIDIA Tegra XUSB pad controller driver in the Linux kernel did not properly     handle return values in certain error conditions. A local attacker could use this to cause a denial of     service (system crash). (CVE-2023-23000)

    It was discovered that Spectre-BHB mitigations were missing for Ampere processors. A local attacker could     potentially use this to expose sensitive information. (CVE-2023-3006)

    It was discovered that the ext4 file system implementation in the Linux kernel did not properly handle     block device modification while it is mounted. A privileged attacker could use this to cause a denial of     service (system crash) or possibly expose sensitive information. (CVE-2023-34256)

    Eric Dumazet discovered that the netfilter subsystem in the Linux kernel did not properly handle DCCP     conntrack buffers in certain situations, leading to an out-of-bounds read vulnerability. An attacker could     possibly use this to expose sensitive information (kernel memory). (CVE-2023-39197)

    It was discovered that the Siano USB MDTV receiver device driver in the Linux kernel did not properly     handle device initialization failures in certain situations, leading to a use-after-free vulnerability. A     physically proximate attacker could use this cause a denial of service (system crash). (CVE-2023-4132)

    Pratyush Yadav discovered that the Xen network backend implementation in the Linux kernel did not properly     handle zero length data request, leading to a null pointer dereference vulnerability. An attacker in a     guest VM could possibly use this to cause a denial of service (host domain crash). (CVE-2023-46838)

    It was discovered that a race condition existed in the AppleTalk networking subsystem of the Linux kernel,     leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service     (system crash) or possibly execute arbitrary code. (CVE-2023-51781)

    Alon Zahavi discovered that the NVMe-oF/TCP subsystem of the Linux kernel did not properly handle connect     command payloads in certain situations, leading to an out-of-bounds read vulnerability. A remote attacker     could use this to expose sensitive information (kernel memory). (CVE-2023-6121)

    It was discovered that the ext4 file system implementation in the Linux kernel did not properly handle the     remount operation in certain cases, leading to a use-after-free vulnerability. A local attacker could use     this to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2024-0775)

    Notselwyn discovered that the netfilter subsystem in the Linux kernel did not properly handle verdict     parameters in certain cases, leading to a use- after-free vulnerability. A local attacker could use this     to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2024-1086)

    It was discovered that a race condition existed in the SCSI Emulex LightPulse Fibre Channel driver in the     Linux kernel when unregistering FCF and re-scanning an HBA FCF table, leading to a null pointer     dereference vulnerability. A local attacker could use this to cause a denial of service (system crash).
