"The version of kernel installed on the remote host is prior to 5.4.156-83.273. It is, therefore, affected by multiple
vulnerabilities as referenced in the ALAS2KERNEL-5.4-2025-099 advisory.

    A race condition accessing file object in the Linux kernel OverlayFS subsystem was found in the way users
    do rename in specific way with OverlayFS. A local user could use this flaw to crash the system.
    (CVE-2021-20321)

    A flaw was found in the Linux kernel. A memory leak in the ccp-ops crypto driver can allow attackers to
    cause a denial of service. This vulnerability is similar with the older CVE-2019-18808. The highest threat
    from this vulnerability is to system availability. (CVE-2021-3744)

    A memory leak flaw was found in the Linux kernel's ccp_run_aes_gcm_cmd() function that allows an attacker
    to cause a denial of service. The vulnerability is similar to the older CVE-2019-18808. The highest threat
    from this vulnerability is to system availability. (CVE-2021-3764)

    An out-of-bounds (OOB) memory write flaw was found in prealloc_elems_and_freelist in kernel/bpf/stackmap.c
    in the bpf in the Linux kernel. In this flaw, the multiplication to calculate the size could lead to an
    integer overflow which could allow a local attacker, with a special user privilege, to gain access to out-
    of-bounds memory leading to a system crash or a leak of internal kernel information. (CVE-2021-41864)
