CVE-2025-37973

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.
