Low technical severity with no CISA KEV confirmation; remediate through the normal risk-based patch cycle unless local exposure raises the priority.
Canonical’s release and source-package findings are shown separately from local repository availability.
A published vendor fix does not prove that a matching update is enabled and installable on a particular asset. Confirm the local package candidate before scheduling remediation.

Patch availableA vulnerability, which was classified as problematic, has been found in Linux Kernel. This issue affects the function unix_sock_destructor/unix_release_sock of the file net/unix/af_unix.c of the component BPF. The manipulation leads to memory leak. It is recommended to apply a patch to fix this issue. The associated identifier of this vulnerability is VDB-211043.

The product does not release or incorrectly releases a resource before it is made available for re-use.
An attacker operating through an adjacent network may attempt exploitation with low privileges. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.
No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.
No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.
CWE-404: Improper Resource Shutdown or Release. The product does not release or incorrectly releases a resource before it is made available for re-use.
