CVE-2026-90366: Linux

Описание

Оригинално описание

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.
