Описание

In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: fix out-of-bounds access during multi-link element defragmentation Currently during the multi-link element defragmentation process, the multi-link element length added to the total IEs length when calculating the length of remaining IEs after the multi-link element in cfg80211_defrag_mle(). This could lead to out-of-bounds access if the multi-link element or its corresponding fragment elements are the last elements in the IEs buffer. To address this issue, correctly calculate the remaining IEs length by deducting the multi-link element end offset from total IEs end offset.

Отчет

A flaw was found in the Linux kernel's cfg80211_defrag_mle() function, where an incorrect calculation of the remaining IEs length could lead to an out-of-bounds memory access during multi-link element (MLE) defragmentation. A malicious beacon or probe response frame containing fragmented MLEs could potentially trigger this issue. This flaw is exploitable in setups where userspace or firmware passes raw Wi-Fi frames to the kernel for parsing (e.g., via softmac drivers), but requires attacker-controlled wireless traffic and a vulnerable parsing path.
