CVE-2026-72024

CVE-2026-72024 concerns the Linux kernel’s mac802154 handling of interfaces under RCU. The issue arises when bulk teardown paths remove entries with list_del(), allowing an asynchronous transmit completion to follow a poisoned list node in ieee802154_wake_queue(). The root cause is the use of lis...

CVE-2026-72012

CVE-2026-72012 affects the Linux kernel’s tracing/osnoise path. The underlying issue is that, during unregistering, a synchronize_rcu() call was missing, risking that RCU readers traversing the instance list may still hold references when the tracer is released. The description states that the vu...
