CVE-2026-72459

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description An issue exists in the AppArmor module where the aa label alloc() function allocates a secid before attempting to allocate or acquire a label proxy. If the proxy step fails, the error handling path only frees the label memory, resulting in a leak of resources previously initialized by the aa label init() function.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
