The version of kernel installed on the remote host is prior to 4.14.318-240.529. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2023-2100 advisory.

  - It was discovered that a nft object or expression could reference a nft set on a different nft table,     leading to a use-after-free once that table was deleted. (CVE-2022-2586)

  - An issue was discovered in the Linux kernel through 5.18.9. A type confusion bug in nft_set_elem_init     (leading to a buffer overflow) could be used by a local attacker to escalate privileges, a different     vulnerability than CVE-2022-32250. (The attacker can obtain root access, but must start with an     unprivileged user namespace to obtain CAP_NET_ADMIN access.) This can be fixed in nft_setelem_parse_data     in net/netfilter/nf_tables_api.c. (CVE-2022-34918)

  - 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)

  - do_tls_getsockopt in net/tls/tls_main.c in the Linux kernel through 6.2.6 lacks a lock_sock call, leading     to a race condition (with a resultant use-after-free or NULL pointer dereference). (CVE-2023-28466)

  - 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 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. NOTE: this is disputed by third parties because the kernel is not intended to defend against     attackers with the stated When modifying the block device while it is mounted by the filesystem access.
    (CVE-2023-34256)

  - 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)

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