CVE-2026-64080

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

Description A use-after-free issue exists in the arm ffa firmware component. The notification handlers retrieve a notifier callback while holding the notify lock, but release the lock before dereferencing the entry. This creates a race condition where a concurrent unregister operation can delete and free the entry, causing the handler to access stale memory.

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