Description OSIDB Bzimport 2026-08-15 06:05:23 UTC
In the Linux kernel, the following vulnerability has been resolved:

mac802154: remove interfaces with RCU list deletion

Queue wake, stop, and disable paths walk local->interfaces under RCU.
The bulk hardware teardown path removes entries with list_del(), so an
asynchronous transmit completion can follow a poisoned list node in
ieee802154_wake_queue().

Use list_del_rcu() as in the single-interface removal path. The following
unregister_netdevice() waits for in-flight RCU readers before freeing the
netdevice, so no separate grace-period wait is needed.
