Last modified

CVE-2026-72024 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. 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.. EPSS estimates a 0.21% chance of exploitation in the next 30 days.
