Vulnerability Title
wifi: ath11k: fix peer HE MCS assignment
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: wifi: ath11k: fix peer HE MCS assignment In ath11k_wmi_send_peer_assoc_cmd(), peer's transmit MCS is sent to firmware as receive MCS while peer's receive MCS sent as transmit MCS, which goes against firmwire's definition. While connecting to a misbehaved AP that advertises 0xffff (meaning not supported) for 160 MHz transmit MCS map, firmware crashes due to 0xffff is assigned to he_mcs->rx_mcs_set field. Ext Tag: HE Capabilities [...] Supported HE-MCS and NSS Set [...] Rx and Tx MCS Maps 160 MHz [...] Tx HE-MCS Map 160 MHz: 0xffff Swap the assignment to fix this issue. As the HE rate control mask is meant to limit our own transmit MCS, it needs to go via he_mcs->rx_mcs_set field. With the aforementioned swapping done, change is needed as well to apply it to the peer's receive MCS.
