In the Linux kernel, the following vulnerability has been resolved: mac802154: fix netdev use-after-free in beacon worker mac802154_beacon_worker()… (CVE-2026-74661)CVE-2026-74661 0 A use-after-free vulnerability in the Linux kernel's mac802154 subsystem was resolved. The issue occurs in the mac802154_beacon_worker() function, which continues to use freed network device data after interface teardown. This happens because the beacon worker drops the RCU read lock but still accesses the sub-interface and embedded wpan_dev, leading to potential memory corruption. The fix involves taking a netdev reference while the request is still protected by RCU and releasing it appropriately to prevent use-after-free.
