Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The Linux kernel contains a flaw in the mt76 module related to out-of-bounds access within the mt76 connac2 mac write txwi 80211() function. A check for frame length is insufficient, potentially allowing access to management fields, specifically mgmt->u.action.u.addba req.capab, leading to a possible out-of-bounds access.
