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

  - The Linux Kernel, the operating system core itself.
    Security Fix(es):An issue was discovered in     fs/fuse/fuse_i.h in the Linux kernel before 5.11.8. A     'stall on CPU' can occur because a retry loop     continually finds the same bad inode, aka     CID-775c5033a0d1.(CVE-2021-28950)An out-of-bounds (OOB)     memory write flaw was found in list_devices in     drivers/md/dm-ioctl.c in the Multi-device driver module     in the Linux kernel before 5.12. A bound check failure     allows an attacker with special user (CAP_SYS_ADMIN)     privilege to gain access to out-of-bounds memory     leading to a system crash or a leak of internal kernel     information. The highest threat from this vulnerability     is to system availability.(CVE-2021-31916)An issue was     discovered in the Linux kernel through 5.2.13.
    nbd_genl_status in drivers/blockbd.c does not check the     nla_nest_start_noflag return value.(CVE-2019-16089)The     bpf verifier in the Linux kernel did not properly     handle mod32 destination register truncation when the     source register was known to be 0. A local attacker     with the ability to load bpf programs could use this     gain out-of-bounds reads in kernel memory leading to     information disclosure (kernel memory), and possibly     out-of-bounds writes that could potentially lead to     code execution. This issue was addressed in the     upstream kernel in commit 9b00f1b78809 ('bpf: Fix     truncation handling for mod32(CVE-2021-3444)An issue     was discovered in the Linux kernel through 5.11.x.
    kernel/bpf/verifier.c performs undesirable     out-of-bounds speculation on pointer arithmetic,     leading to side-channel attacks that defeat Spectre     mitigations and obtain sensitive information from     kernel memory. Specifically, for sequences of pointer     arithmetic operations, the pointer modification     performed by the first operation is not correctly     accounted for when restricting subsequent     operations.(CVE-2021-29155)net/bluetooth/hci_request.c     in the Linux kernel through 5.12.2 has a race condition     for removal of the HCI controller.
    (CVE-2021-32399)kernel/bpf/verifier.c in the Linux     kernel through 5.12.1 performs undesirable speculative     loads, leading to disclosure of stack content via     side-channel attacks, aka CID-801c6058d14a. The     specific concern is not protecting the BPF stack area     against speculative loads. Also, the BPF stack can     contain uninitialized data that might represent     sensitive information previously operated on by the     kernel.(CVE-2021-31829)The Linux kernel before 5.11.14     has a use-after-free in cipso_v4_genopt in     net/ipv4/cipso_ipv4.c because the CIPSO and CALIPSO     refcounting for the DOI definitions is mishandled, aka     CID-ad5d07f4a9cd. This leads to writing an arbitrary     value.(CVE-2021-33033)Use After Free vulnerability in     nfc sockets in the Linux Kernel before 5.12.4 allows     local attackers to elevate their privileges. In typical     configurations, the issue can only be triggered by a     privileged local user with the CAP_NET_RAW     capability.(CVE-2021-23134)A memory leak vulnerability     was found in Linux kernel in     llcp_sock_connect(CVE-2020-25672)A vulnerability was     found in Linux Kernel, where a refcount leak in     llcp_sock_connect() causing use-after-free which might     lead to privilege escalations.(CVE-2020-25671)A     vulnerability was found in Linux Kernel where refcount     leak in llcp_sock_bind() causing use-after-free which     might lead to privilege escalations.(CVE-2020-25670)In     the Linux kernel before 5.12.4,     net/bluetooth/hci_event.c has a use-after-free when     destroying an hci_chan, aka CID-5c4c8c954409. This     leads to writing an arbitrary value.(CVE-2021-33034)

  - u'Specifically timed and handcrafted traffic can cause internal errors 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' in Snapdragon Auto, Snapdragon Compute, Snapdragon Connectivity, Snapdragon     Consumer IOT, Snapdragon Industrial IOT, Snapdragon Mobile, Snapdragon Voice & Music, Snapdragon     Wearables, Snapdragon Wired Infrastructure and Networking in APQ8053, IPQ4019, IPQ8064, MSM8909W,     MSM8996AU, QCA9531, QCN5502, QCS405, SDX20, SM6150, SM7150 (CVE-2020-3702)

  - Use After Free vulnerability in nfc sockets in the Linux Kernel before 5.12.4 allows local attackers to     elevate their privileges. In typical configurations, the issue can only be triggered by a privileged local     user with the CAP_NET_RAW capability. (CVE-2021-23134)

  - A heap-based buffer overflow flaw was found in the Linux kernel FireDTV media card driver, where the user     calls the CA_SEND_MSG ioctl. This flaw allows a local user of the host machine to crash the system or     escalate privileges on the system. The highest threat from this vulnerability is to confidentiality,     integrity, as well as system availability. (CVE-2021-42739)

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 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:0293-1 advisory.

  - Use After Free vulnerability in nfc sockets in the Linux Kernel before 5.12.4 allows local attackers to     elevate their privileges. In typical configurations, the issue can only be triggered by a privileged local     user with the CAP_NET_RAW capability. (CVE-2021-23134)

  - A flaw in the Linux kernel's implementation of RDMA communications manager listener code allowed an     attacker with local access to setup a socket to listen on a high port allowing for a list element to be     used after free. Given the ability to execute code, a local attacker could leverage this use-after-free to     crash the system or possibly escalate privileges on the system. (CVE-2021-4028)

  - A use-after-free flaw was found in cgroup1_parse_param in kernel/cgroup/cgroup-v1.c in the Linux kernel's     cgroup v1 parser. A local attacker with a user privilege could cause a privilege escalation by exploiting     the fsconfig syscall parameter leading to a container breakout and a denial of service on the system.
    (CVE-2021-4154)

  - A heap-based buffer overflow flaw was found in the Linux kernel FireDTV media card driver, where the user     calls the CA_SEND_MSG ioctl. This flaw allows a local user of the host machine to crash the system or     escalate privileges on the system. The highest threat from this vulnerability is to confidentiality,     integrity, as well as system availability. (CVE-2021-42739)

  - A heap-based buffer overflow flaw was found in the way the legacy_parse_param function in the Filesystem     Context functionality of the Linux kernel verified the supplied parameters length. An unprivileged (in     case of unprivileged user namespaces enabled, otherwise needs namespaced CAP_SYS_ADMIN privilege) local     user able to open a filesystem that does not support the Filesystem Context API (and thus fallbacks to     legacy handling) could use this flaw to escalate their privileges on the system. (CVE-2022-0185)

The remote SUSE Linux SLES12 / SLES_SAP12 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:0327-1 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)

  - Insufficient access control in the Intel(R) PROSet/Wireless WiFi Software driver before version 21.10 may     allow an unauthenticated user to potentially enable denial of service via adjacent access. (CVE-2019-0136)
