"It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2024-603 advisory.

    2024-06-06: CVE-2024-26621 was added to this advisory.

    2024-06-06: CVE-2024-27417 was added to this advisory.

    2024-05-23: CVE-2024-26782 was added to this advisory.

    A vulnerability was discovered in the Linux kernel's IPv4 networking stack. Under certain conditions,
    MPTCP and NetLabel can be configured in a way that triggers a double free memory error in
    net/ipv4/af_inet.c:inet_sock_destruct(). This may lead to a system crash, denial of service, or potential
    arbitrary code execution. (CVE-2024-1627)

    In the Linux kernel, the following vulnerability has been resolved:

    mm: huge_memory: don't force huge page alignment on 32 bit (CVE-2024-26621)

    In the Linux kernel, the following vulnerability has been resolved:

    mptcp: fix double-free on socket dismantle (CVE-2024-26782)

    In the Linux kernel, the following vulnerability has been resolved:

    ipv6: fix potential struct net leak in inet6_rtm_getaddr() (CVE-2024-27417)

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.");
