CVE-2024-49939

The CVE-2024-49939 entry concerns the Linux kernel wifi driver rtw89 (rtw89_wow_resume and ieee80211_reconfig flow). When SER L2 occurs during WoWLAN resume, the add-interface path can run twice due to a failed rtw89_wow_resume(), leading to a second list_add and a kernel panic. The available sou...
