mac802154: remove interfaces with RCU list deletion

Noroxi assessment

Priority: Monitor (action score 31/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.12% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 2039f27b1a0c997137a5de7f8a3cee0e80fbf952, 4bf231f459b542414629b64f63d5cad6701bd07c, 539dfcf69105d8d3d4d677b71de6e5ede2e6dfa0.

Low priority for now. Upgrade to Linux Linux 2039f27b1a0c997137a5de7f8a3cee0e80fbf952, 4bf231f459b542414629b64f63d5cad6701bd07c, 539dfcf69105d8d3d4d677b71de6e5ede2e6dfa0 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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.
