CVE-2024-50005

Stale memory access via post-RCU request dereference

Published Oct 21, 2024 · Updated May 11, 2026

Use-after-free in the Linux kernel mac802154 subsystem allows local users to access stale or freed memory during an IEEE 802.15.4 scan. mac802154_scan_worker reads scan_req->type after leaving its RCU read-side critical section, so the scan request can change or be freed before the read. Reachability requires low-privileged local access and an active mac802154 scan; consequences are bounded to unpredictable kernel memory access.
