A patch is available and should be applied to affected linux-aws kernel versions. The vendor advisory from Ubuntu confirms that this issue has been fixed. Users should update to the patched kernel versions to mitigate this vulnerability.
Description
A high-severity vulnerability (CVE-2026-72024) in the Linux kernel's mac802154 subsystem was resolved. The issue involves improper removal of interfaces using list_del() instead of list_del_rcu(), which can lead to use-after-free conditions during asynchronous transmit completions. The flaw affects specific linux-aws kernel versions. A patch is available that corrects the interface removal method and relies on unregister_netdevice() to safely wait for RCU readers before freeing resources.
