CVE-2026-23410

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

Description The Linux kernel contains a race condition within the AppArmor subsystem that can lead to a use-after-free situation. This occurs because rawdata inodes are not properly reference counted, allowing an attacker to manipulate the system such that memory is accessed after it has been freed. Specifically, an attacker can open rawdata files while simultaneously removing the last reference to the rawdata, leading to a dangling pointer in seq rawdata open() and subsequent access to freed memory.

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