The version of kernel installed on the remote host is prior to 5.4.247-161.349. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.4-2023-047 advisory.

    A flaw was found in the x86 KVM subsystem in kvm_steal_time_set_preempted in arch/x86/kvm/x86.c in the     Linux kernel. Unprivileged guest users can compromise the guest kernel because TLB flush operations are     mishandled in certain KVM_VCPU_PREEMPTED situations. (CVE-2022-39189)

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

    btrfs: unset reloc control if transaction commit fails in prepare_to_relocate() (CVE-2022-50067)

    There is a potential deadlock in the eBPF subsystem in the Linux kernel.

    The default sysctl configuration kernel.unprivileged_bpf_disabled on Amazon Linux does not allow     unprivileged users to use eBPF. (CVE-2023-0160)

    A denial of service problem was found, due to a possible recursive locking scenario, resulting in a     deadlock in table_clear in drivers/md/dm-ioctl.c in the Linux Kernel Device Mapper-Multipathing sub-     component. (CVE-2023-2269)

    A heap out-of-bounds write vulnerability in the Linux Kernel ipvlan network driver can be exploited to     achieve local privilege escalation.

    The out-of-bounds write is caused by missing skb->cb  initialization in the ipvlan network driver. The     vulnerability is reachable if CONFIG_IPVLAN is enabled.

    We recommend upgrading past commit 90cbed5247439a966b645b34eb0a2e037836ea8e. (CVE-2023-3090)

    A use after free vulnerability was found in prepare_to_relocate in fs/btrfs/relocation.c in btrfs in the     Linux Kernel. This possible flaw can be triggered by calling btrfs_ioctl_balance() before calling     btrfs_ioctl_defrag(). (CVE-2023-3111)

    A use-after-free flaw was found in r592_remove in drivers/memstick/host/r592.c in media access in the     Linux Kernel. This flaw allows a local attacker to crash the system at device disconnect, possibly leading     to a kernel information leak. (CVE-2023-3141)

    An out of bounds (OOB) memory access flaw was found in the Linux kernel in relay_file_read_start_pos in     kernel/relay.c in the relayfs. This flaw could allow a local attacker to crash the system or leak kernel     internal information. (CVE-2023-3268)

    An issue was discovered in the Linux kernel before 6.3.3. There is an out-of-bounds read in crc16 in     lib/crc16.c when called from fs/ext4/super.c because ext4_group_desc_csum does not properly check an     offset. (CVE-2023-34256)

    A use-after-free flaw was found in vcs_read in drivers/tty/vt/vc_screen.c in vc_screen in the Linux     Kernel. In this flaw an attacker with local user access may lead to a system crash or a leak of internal     kernel information. (CVE-2023-3567)

    An issue was discovered in fl_set_geneve_opt in net/sched/cls_flower.c in the Linux kernel before 6.3.7.
    It allows an out-of-bounds write in the flower classifier code via TCA_FLOWER_KEY_ENC_OPTS_GENEVE packets.
    This may result in denial of service or privilege escalation. (CVE-2023-35788)

    serial: 8250: Reinit port->pm on port specific driver unbind (CVE-2023-53176)

    lib: cpu_rmap: Avoid use after free on rmap->obj array entries (CVE-2023-53484)

    serial: arc_uart: fix of_iomap leak in `arc_serial_probe` (CVE-2023-53719)

    A use-after-free flaw was found in the __ext4_remount in fs/ext4/super.c in ext4 in the Linux kernel. This     flaw allows a local user to cause an information leak problem while freeing the old quota file names     before a potential failure, leading to a use-after-free. (CVE-2024-0775)
