Description

A flaw was found in the Linux kernel's mac80211 Wi-Fi subsystem. This vulnerability arises from incorrect handling of Multi-Link Element (MLE) defragmentation. When a reconf or EPCS (Enhanced Power Save) MLE is present in a non-transmitted profile, the defragmentation routine uses an incorrect pointer. This can lead to a heap data overrun, which is a form of memory corruption that may result in system instability or unexpected behavior.
