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.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
