Description OSIDB Bzimport 2026-08-10 12:35:17 UTC 
In the Linux kernel, the following vulnerability has been resolved:

wifi: mt76: mt7915: guard HE capability lookups

mt7915_mcu_bss_he_tlv() and mt7915_mcu_sta_bfer_tlv() both run after
checking HE support, then dereference the HE PHY capability returned by
mt76_connac_get_he_phy_cap(). That helper can return NULL when no
capability entry matches the vif type.

Fetch the capability before appending the TLV and skip the HE-specific
setup when no matching capability is available.
