"The CentOS Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the
TuxCare CENTOS7:CLSA-2024:1728935304 advisory.

  - A use-after-free exists in the Linux Kernel in tc_new_tfilter that could allow a local attacker to gain
    privilege escalation. The exploit requires unprivileged user namespaces. We recommend upgrading past
    commit 04c2a47ffb13c29778e2a14e414ad4cb5a5db4b5 (CVE-2022-1055)

  - In ip_check_mc_rcu of igmp.c, there is a possible use after free due to improper locking. This could lead
    to local escalation of privilege when opening and closing inet sockets with no additional execution
    privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android
    kernelAndroid ID: A-112551163References: Upstream kernel (CVE-2022-20141)

  - Product: AndroidVersions: Android kernelAndroid ID: A-224546354References: Upstream kernel
    (CVE-2022-20368)

  - An integer coercion error was found in the openvswitch kernel module. Given a sufficiently large number of
    actions, while copying and reserving memory for a new action of a new flow, the reserve_sfa_size()
    function does not return -EMSGSIZE as expected, potentially leading to an out-of-bounds write access. This
    flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-2639)

  - Improper Update of Reference Count vulnerability in net/sched of Linux Kernel allows local attacker to
    cause privilege escalation to root. This issue affects: Linux Kernel versions prior to 5.18; version 4.14
    and later versions. (CVE-2022-29581)

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