CVE-2022-50665

Estado: AplazadaAlta (7.1)—

In the Linux kernel, the following vulnerability has been resolved:

wifi: ath11k: fix failed to find the peer with peer_id 0 when disconnected

It has a fail log which is ath11k_dbg in ath11k_dp_rx_process_mon_status(), as below, it will not print when debug_mask is not set ATH11K_DBG_DATA. ath11k_dbg(ab, ATH11K_DBG_DATA, "failed to find the peer with peer_id %d\n", ppdu_info.peer_id);

When run scan with station disconnected, the peer_id is 0 for case HAL_RX_MPDU_START in ath11k_hal_rx_parse_mon_status_tlv() which called from ath11k_dp_rx_process_mon_status(), and the peer_id of ppdu_info is reset to 0 in the while loop, so it does not match condition of the check "if (ppdu_info->peer_id == HAL_INVALID_PEERID" in the loop, and then the log "failed to find the peer with peer_id 0" print after the check in the loop, it is below call stack when debug_mask is set ATH11K_DBG_DATA.

The reason is this commit 01d2f285e3e5 ("ath11k: decode HE status tlv") add "memset(ppdu_info, 0, sizeof(struct hal_rx_mon_ppdu_info))" in ath11k_dp_rx_process_mon_status(), but the commit does not initialize the peer_id to HAL_INVALID_PEERID, then lead the check mis-match.

Reset the default value to HAL_INVALID_PEERID each time after memset of ppdu_info as well as others memset which existed in function ath11k_dp_rx_process_mon_status(), then the failed log disappeared.
