The version of kernel installed on the remote host is prior to 5.10.162-141.675. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.10-2023-025 advisory.

  - Guests can trigger NIC interface reset/abort/crash via netback It is possible for a guest to trigger a NIC     interface reset/abort/crash in a Linux based network backend by sending certain kinds of packets. It     appears to be an (unwritten?) assumption in the rest of the Linux network stack that packet protocol     headers are all contained within the linear section of the SKB and some NICs behave badly if this is not     the case. This has been reported to occur with Cisco (enic) and Broadcom NetXtrem II BCM5780 (bnx2x)     though it may be an issue with other NICs/drivers as well. In case the frontend is sending requests with     split headers, netback will forward those violating above mentioned assumption to the networking core,     resulting in said misbehavior. (CVE-2022-3643)

  - A vulnerability classified as problematic has been found in Linux Kernel. This affects the function     fib_nh_match of the file net/ipv4/fib_semantics.c of the component IPv4 Handler. The manipulation leads to     out-of-bounds read. It is possible to initiate the attack remotely. It is recommended to apply a patch to     fix this issue. The identifier VDB-210357 was assigned to this vulnerability. (CVE-2022-3435)

  - A vulnerability was found in Linux Kernel. It has been declared as problematic. Affected by this     vulnerability is the function follow_page_pte of the file mm/gup.c of the component BPF. The manipulation     leads to race condition. The attack can be launched remotely. It is recommended to apply a patch to fix     this issue. The identifier VDB-211921 was assigned to this vulnerability. (CVE-2022-3623)

  - A stack overflow flaw was found in the Linux kernel's SYSCTL subsystem in how a user changes certain     kernel parameters and variables. This flaw allows a local user to crash or potentially escalate their     privileges on the system. (CVE-2022-4378)

  - Guests can trigger deadlock in Linux netback driver T[his CNA information record relates to multiple CVEs;
    the text explains which aspects/vulnerabilities correspond to which CVE.] The patch for XSA-392 introduced     another issue which might result in a deadlock when trying to free the SKB of a packet dropped due to the     XSA-392 handling (CVE-2022-42328). Additionally when dropping packages for other reasons the same deadlock     could occur in case of netpoll being active for the interface the xen-netback driver is connected to     (CVE-2022-42329). (CVE-2022-42328, CVE-2022-42329)

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