CVE-2026-23408

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

Description The Linux kernel contains a flaw within the apparmor subsystem related to a double free of ns name in the aa replace profiles() function. Specifically, if ns name is NULL after unpacking user data, and ent->ns name contains an ns name, the ent->ns name is assigned to ns name. However, ent->ns name is freed, and then ns name is freed again, leading to a double free condition.

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