The version of kernel installed on the remote host is prior to 4.14.252-195.481. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2021-1719 advisory.

    A flaw was found in the Linux kernel. A corrupted timer tree caused the task wakeup to be missing in the     timerqueue_add function in lib/timerqueue.c. This flaw allows a local attacker with special user     privileges to cause a denial of service, slowing and eventually stopping the system while running OSP. The     highest threat from this vulnerability is system availability. (CVE-2021-20317)

    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 use-after-free in the Linux kernel USB High Speed Mobile Devices functionality was found in the way     user detaches USB device. A local user could use this flaw to crash the system or escalate their     privileges on the system. (CVE-2021-37159)

    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)

    A flaw was found in the Linux kernel. The cBPF JIT compiler may produce machine code with incorrect     branches. This flaw allows an unprivileged user to craft anomalous machine code, where the control flow is     hijacked to execute arbitrary kernel code. The highest threat from this vulnerability is to     confidentiality, integrity, as well as system availability. (CVE-2021-38300)

    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)

    phy: mdio: fix memory leak (CVE-2021-47416)

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

    net_sched: fix NULL deref in fifo_set_limit() (CVE-2021-47418)

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