CVE-2023-54300: wifi: ath9k: avoid referencing uninit memory in ath9k_wmi_ctrl_rx

—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 0/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.23% (FIRST EPSS).
  • Fixed version: Linux Linux 0bc12e41af4e3ae1f0efecc377f0514459df0707, 250efb4d3f5b32a115ea6bf25437ba44a1b3c04f, 28259ce4f1f1f9ab37fa817756c89098213d2fc0.

Low priority for now. Upgrade to Linux Linux 0bc12e41af4e3ae1f0efecc377f0514459df0707, 250efb4d3f5b32a115ea6bf25437ba44a1b3c04f, 28259ce4f1f1f9ab37fa817756c89098213d2fc0 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In 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.
