It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-330 advisory.

  - A division-by-zero error on some AMD processors can potentially return speculative data resulting in loss     of confidentiality. (CVE-2023-20588)

  - A flaw was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem). This issue     may allow a malicious user with CAP_NET_ADMIN privileges to directly dereference a NULL pointer in     xfrm_update_ae_params(), leading to a possible kernel crash and denial of service. (CVE-2023-3772)

  - A flaw was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem). This issue     may allow a malicious user with CAP_NET_ADMIN privileges to cause a 4 byte out-of-bounds read of     XFRMA_MTIMER_THRESH when parsing netlink attributes, leading to potential leakage of sensitive heap data     to userspace. (CVE-2023-3773)

  - A use-after-free flaw was found in the Linux kernel's netfilter in the way a user triggers the     nft_pipapo_remove function with the element, without a NFT_SET_EXT_KEY_END. This issue could allow a local     user to crash the system or potentially escalate their privileges on the system. (CVE-2023-4004)

  - A use-after-free flaw was found in net/sched/cls_fw.c in classifiers (cls_fw, cls_u32, and cls_route) in     the Linux Kernel. This flaw allows a local attacker to perform a local privilege escalation due to     incorrect handling of the existing filter, leading to a kernel information leak issue. (CVE-2023-4128)

  - A use-after-free flaw was found in the Linux kernel's Netfilter functionality when adding a rule with     NFTA_RULE_CHAIN_ID. This flaw allows a local user to crash or escalate their privileges on the system.
    (CVE-2023-4147)

  - A flaw was found in the Linux kernel's TUN/TAP functionality. This issue could allow a local user to     bypass network filters and gain unauthorized access to some resources. The original patches fixing     CVE-2023-1076 are incorrect or incomplete. The problem is that the following upstream commits -     a096ccca6e50 (tun: tun_chr_open(): correctly initialize socket uid), - 66b2c338adce (tap: tap_open():
    correctly initialize socket uid), pass inode->i_uid to sock_init_data_uid() as the last parameter and     that turns out to not be accurate. (CVE-2023-4194)

  - A flaw was found in the exFAT driver of the Linux kernel. The vulnerability exists in the implementation     of the file name reconstruction function, which is responsible for reading file name entries from a     directory index and merging file name parts belonging to one file into a single long file name. Since the     file name characters are copied into a stack variable, a local privileged attacker could use this flaw to     overflow the kernel stack. (CVE-2023-4273)

  - A division-by-zero error on some AMD processors can potentially return speculative data resulting in loss     of confidentiality. (CVE-2023-20588) (CVE-2023-34319)

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