CVE-2026-74368: wifi: ath12k: fix memory leak in ath12k_wifi7_dp_rx_h_verify_tkip_mic()

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: 0.16% (FIRST EPSS).
  • Fixed version: Linux Linux 5187a92099778501f21af76ed6c8415d128e7298, 55c6f05b667726d2da5fd011d646fb48ce5b6b9c, 6.12.114.

Low priority for now. Upgrade to Linux Linux 5187a92099778501f21af76ed6c8415d128e7298, 55c6f05b667726d2da5fd011d646fb48ce5b6b9c, 6.12.114 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: fix memory leak in ath12k_wifi7_dp_rx_h_verify_tkip_mic() In ath12k_wifi7_dp_rx_h_verify_tkip_mic(), the call to ath12k_dp_rx_check_nwifi_hdr_len_valid() may return false when the NWIFI header length is invalid, causing the function to abort early with -EINVAL. When this happens, the error propagates to ath12k_wifi7_dp_rx_h_defrag(), which clears first_frag by setting it to NULL. As a result, the corresponding MSDU is no longer referenced by the defragmentation path and is never freed. This leads to a memory leak for the affected MSDU on this error path. Proper cleanup is required to ensure the MSDU is released when header validation fails during TKIP MIC verification. Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.1.c5-00302-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.115823.3
