CVE-2026-98332

The Linux kernel contains a vulnerability in the wifi: mac80211 component. The function ieee80211_tdls_oper() can incorrectly operate on an AP station if it is confused for a TDLS peer . This leads to various warnings when the AP station is subsequently removed or at a later point in time. The fi...
