CVE-2026-64092

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

Description A reference leak exists in the batman-adv tp meter component during receiver shutdown. The receiver shutdown timer handler, batadv tp receiver shutdown(), is responsible for releasing the tp vars reference. However, flawed coordination logic between this handler and batadv tp stop all() can lead to a failure in releasing the reference. Specifically, if the timer has already expired, batadv tp stop all() skips its batadv tp vars put() call, and batadv tp receiver shutdown() also fails to release its reference. This is addressed by using an atomic variable receiving and the atomic xchg() function to ensure that only one side is responsible for releasing the tp vars timer reference.

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