CVE-2026-64095

A flaw was found in the Linux kernel's batman-adv module, which handles bridge loop avoidance. A race condition allows the bla.numrequests counter to be decremented multiple times due to non-atomic operations. This can lead to an inconsistent state within the kernel, potentially enabling a local...

CVE-2026-64095

In the Linux kernel, the following vulnerability has been resolved: batman-adv: bla: avoid double decrement of bla.numrequests The bla.numrequests is increased when no requestsent was in progress. And it is decremented in various places announcement was received, backbone is purged, periodic work...

CVE-2026-64095

Concrete details confirm CVE-2026-64095 affects Linux kernel batman-adv (bla.num_requests) where double decrement occurs due to non-atomic checks of request_sent and bla.num_requests. The root cause: several code paths modify state and counts without atomic synchronization, allowing TOCTOU races....
