The remote Ubuntu 22.04 LTS host has a package installed that is affected by a vulnerability as referenced in the USN-6576-1 advisory.

    Lonial Con discovered that the netfilter subsystem in the Linux kernel did not properly handle an expired     catchall element in some situations, leading to a use-after-free vulnerability. A local attacker could use     this to cause a denial of service (system crash) or possibly execute arbitrary code.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to     achieve local privilege escalation. The function nft_trans_gc_catchall did not remove the catchall set     element from the catchall_list when the argument sync is true, making it possible to free a catchall set     element many times. We recommend upgrading past commit 93995bf4af2c5a99e2a87f0cd5ce547d31eb7630.
    (CVE-2023-6111)

Note that Nessus relies on the presence of the package as reported by the vendor.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-461 advisory.
