CVE-2026-23281

A flaw was found in the Linux kernel's Marvell Libertas Wi-Fi driver. This vulnerability, a use-after-free, occurs because the system does not properly synchronize the freeing of memory with ongoing timer operations. If a timer attempts to access resources after they have been released, it can le...

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...

PT-2026-27646

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A flaw exists in the Linux kernel’s wifi subsystem, specifically within the libertas driver.
