CVE-2024-47724

Kernel memory corruption via beacon-triggered atomic sleep

Published Oct 21, 2024 · Updated Aug 5, 2026

Use-after-free in Linux 6.10 before 6.10.13 and 6.11 before 6.11.2 allows physically proximate attackers to corrupt kernel memory via Wi-Fi beacons. During an ath11k access-point color change, ath11k_bcn_tx_status_event calls the sleeping ath11k_wmi_cmd_send path inside an RCU read-side critical section, allowing teardown to free objects still in use. Radio-range beacon injection requires no association or credentials and can expose or overwrite kernel memory, panic the host, or wedge the wireless device.
