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...
