CVE-2026-74489

CVE-2026-74489 describes a use-after-free in the Linux kernel’s wifi mac80211 stack (tid_tx) during BA session stop. The bug occurs when ieee80211_stop_tx_ba_cb() hands tid_tx to kfree_rcu() via ieee80211_remove_tid_tx(), then reads tid_tx->ndp after dropping sta->lock. The read happens out...
