CVE-2023-52800 is an improper resource-locking flaw in the Linux kernel ath11k Wi-Fi driver. HTT packet-log handling accesses active physical-device state through ath11k_mac_get_ar_by_pdev_id() without entering an RCU read-side critical section, despite that state being RCU-protected. Concurrent removal or reclamation of the referenced device can therefore create a use-after-free condition. The issue was introduced in Linux kernel 5.6 and affects the ath11k receive-path implementation.
