The version of kernel installed on the remote host is prior to 5.15.50-23.125. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.15-2022-002 advisory.

    A use-after-free flaw was found in fs/ext4/namei.c:dx_insert_block() in the Linux kernel's filesystem sub-     component. This flaw allows a local attacker with a user privilege to cause a denial of service.
    (CVE-2022-1184)

    With shadow paging enabled, the INVPCID instruction results in a call to kvm_mmu_invpcid_gva. If INVPCID     is executed with CR0.PG=0, the invlpg callback is not set and the result is a NULL pointer dereference.
    (CVE-2022-1789)

    A NULL pointer dereference flaw was found in the Linux kernel's KVM module, which can lead to a denial of     service in the x86_emulate_insn in arch/x86/kvm/emulate.c. This flaw occurs while executing an illegal     instruction in guest in the Intel CPU. (CVE-2022-1852)

    A use-after-free vulnerability was found in the Linux kernel's Netfilter subsystem in     net/netfilter/nf_tables_api.c. This flaw allows a local attacker with user access to cause a privilege     escalation issue. (CVE-2022-1966)

    No description is available for this CVE. (CVE-2022-1972)

    A use-after-free flaw was found in the Linux kernel in log_replay in fs/ntfs3/fslog.c in the NTFS journal.
    This flaw allows a local attacker to crash the system and leads to a kernel information leak problem.
    (CVE-2022-1973)

    A vulnerability was found in the Linux kernel's nft_set_desc_concat_parse() function .This flaw allows an     attacker to trigger a buffer overflow via nft_set_desc_concat_parse() , causing a denial of service and     possibly to run code. (CVE-2022-2078)

    A flaw was found in hw. Incomplete cleanup of multi-core shared buffers for some Intel(r) Processors may     allow an authenticated user to enable information disclosure via local access. (CVE-2022-21123)

    A flaw was found in hw. Incomplete cleanup of microarchitectural fill buffers on some Intel(r) Processors     may allow an authenticated user to enable information disclosure via local access. (CVE-2022-21125)

    A flaw was found in hw. Incomplete cleanup in specific special register write operations for some     Intel Processors may allow an authenticated user to enable information disclosure via local access.
    (CVE-2022-21166)

    net/netfilter/nf_tables_api.c in the Linux kernel through 5.18.1 allows a local user (able to create     user/net namespaces) to escalate privileges to root because an incorrect NFT_STATEFUL_EXPR check leads to     a use-after-free. (CVE-2022-32250)

    An issue was discovered in the Linux kernel through 5.18.3 on powerpc 32-bit platforms. There is a buffer     overflow in ptrace PEEKUSER and POKEUSER (aka PEEKUSR and POKEUSR) when accessing floating point     registers. (CVE-2022-32981)

    rpmsg_virtio_add_ctrl_dev in drivers/rpmsg/virtio_rpmsg_bus.c in the Linux kernel before 5.18.4 has a     double free. (CVE-2022-34494)

    rpmsg_probe in drivers/rpmsg/virtio_rpmsg_bus.c in the Linux kernel before 5.18.4 has a double free.
