- Summary
- wifi: ath12k: fix memory leak in ath12k_wifi7_dp_rx_h_verify_tkip_mic()
- Details
-
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
