How to fix?

There is no fixed version for RHEL:8 kernel-debug-modules-internal.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-debug-modules-internal package and not the kernel-debug-modules-internal package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

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.
