The version of kernel installed on the remote host is prior to 5.15.106-64.140. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.15-2023-016 advisory.

    2024-07-03: CVE-2023-1611 was added to this 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)

    A use-after-free vulnerability was found in __nfs42_ssc_open() in fs/nfs/nfs4file.c in the Linux kernel.
    This flaw allows an attacker to conduct a remote denial of service. (CVE-2022-4379)

    A use-after-free flaw was found in btrfs_search_slot in fs/btrfs/ctree.c in btrfs in the Linux Kernel.This     flaw allows an attacker to crash the system and possibly cause a kernel information lea (CVE-2023-1611)

    An out-of-bounds write vulnerability was found in the Linux kernel's SLIMpro I2C device driver. The     userspace data->block[0] variable was not capped to a number between 0-255 and was used as the size of a     memcpy, possibly writing beyond the end of dma_buffer. This flaw could allow a local privileged user to     crash the system or potentially achieve code execution. (CVE-2023-2194)

    do_tls_getsockopt in net/tls/tls_main.c in the Linux kernel through 6.2.6 lacks a lock_sock call, leading     to a race condition (with a resultant use-after-free or NULL pointer dereference). (CVE-2023-28466)

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

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