It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-251 advisory.

  - A use-after-free flaw was found in the Netfilter subsystem of the Linux kernel when processing named and     anonymous sets in batch requests, which can lead to performing arbitrary reads and writes in kernel     memory. This flaw allows a local user with CAP_NET_ADMIN capability to crash or potentially escalate their     privileges on the system. (CVE-2023-3117)

  - Linux Kernel nftables Use-After-Free Local Privilege Escalation Vulnerability; `nft_chain_lookup_byid()`     failed to check whether a chain was active and CAP_NET_ADMIN is in any user or network namespace     (CVE-2023-31248)

  - A use-after-free vulnerability was found in the Linux kernel's netfilter subsystem in     net/netfilter/nf_tables_api.c. Mishandled error handling with NFT_MSG_NEWRULE makes it possible to use a     dangling pointer in the same transaction causing a use-after-free vulnerability. This flaw allows a local     attacker with user access to cause a privilege escalation issue. We recommend upgrading past commit     1240eb93f0616b21c675416516ff3d74798fdc97. (CVE-2023-3390)

  - Linux Kernel nftables Out-Of-Bounds Read/Write Vulnerability; nft_byteorder poorly handled vm register     contents when CAP_NET_ADMIN is in any user or network namespace (CVE-2023-35001)

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