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

wifi: cfg80211: handle 2x996 RU allocation in cfg80211_calculate_bitrate_he()

Currently NL80211_RATE_INFO_HE_RU_ALLOC_2x996 is not handled in
cfg80211_calculate_bitrate_he(), leading to below warning:

kernel: invalid HE MCS: bw:6, ru:6
kernel: WARNING: CPU: 0 PID: 2312 at net/wireless/util.c:1501 cfg80211_calculate_bitrate_he+0x22b/0x270 [cfg80211]

Fix it by handling 2x996 RU allocation in the same way as 160 MHz bandwidth.
