In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7996: reserve space for the CSA-abort countdown TLV
When a CSA countdown is active, mt7996_mcu_beacon_cntdwn() emits two
bss_bcn_cntdwn_tlv entries (the CSA countdown and the CCA-abort BCC), but
MT7996_BEACON_UPDATE_SIZE only reserved one. With MBSSID enabled and a
near-maximum beacon template the extra 8 bytes could push the offload
command past MT7996_MAX_BSS_OFFLOAD_SIZE and trigger skb_over_panic().
Reserve room for both countdown TLVs.
