CVE-2026-64093

The CVE concerns batman-adv (Linux kernel) where tp_meter cleanup caused a potential re-arm of a timer due to two-step deletion. batadv_tp_sender_cleanup() called timer_delete_sync() followed by timer_delete(); the fix replaces both calls with a single timer_shutdown_sync() that waits for any run...

CVE-2026-64091

CVE-2026-64091 affects batman-adv in the Linux kernel, addressing a TOCTOU race in the TT-based TVLV generation for reported VLANs. The issue arises because the buffer used to hold VLAN entries is sized based on a prefilter that may undercount or overcount VLANs during parallel updates, while the...

CVE-2026-64092

The CVE-2026-64092 issue affects the Linux kernel’s batman-adv module (tp_meter). The root cause is flawed coordination between receiver shutdown and batadv_tp_stop_all(), allowing a tp_vars reference leak when batadv_tp_receiver_shutdown() fails to release its reference if a timer had already ex...
