GHSA-2337-FJ37-R35Q
Vulnerability from github – Published: 2025-12-30 15:30 – Updated: 2025-12-30 15:30In the Linux kernel, the following vulnerability has been resolved:
wifi: ath9k: avoid referencing uninit memory in ath9k_wmi_ctrl_rx
For the reasons also described in commit b383e8abed41 ("wifi: ath9k: avoid uninit memory read in ath9k_htc_rx_msg()"), ath9k_htc_rx_msg() should validate pkt_len before accessing the SKB.
For example, the obtained SKB may have been badly constructed with pkt_len = 8. In this case, the SKB can only contain a valid htc_frame_hdr but after being processed in ath9k_htc_rx_msg() and passed to ath9k_wmi_ctrl_rx() endpoint RX handler, it is expected to have a WMI command header which should be located inside its data payload.
Implement sanity checking inside ath9k_wmi_ctrl_rx(). Otherwise, uninit memory can be referenced.
Tested on Qualcomm Atheros Communications AR9271 802.11n .
Found by Linux Verification Center (linuxtesting.org) with Syzkaller.
