CVE-2026-23281

In CVE-2026-23281, the Linux kernel Libertus wifi driver (lbs_free_adapter) uses non‑synchronous timer_delete() for command_timer and tx_lockup_timer, risking use‑after‑free if a timer callback runs during free. The callbacks (lbs_cmd_timeout_handler, lbs_tx_lockup_handler) access freed fields, c...
