CVE-2022-48875

CVE-2022-48875 affects the Linux kernel’s wireless stack (mac80211). The vulnerability arises when AMPDU start handling in the driver path can encounter a NULL sdata during deauthentication, leading to a NULL dereference. Specifically, ieee80211_tx_ba_session_handle_start() may receive NULL for s...
