Vulnerability from github – Published: 2024-10-21 18:30 – Updated: 2025-11-03 21:31In the Linux kernel, the following vulnerability has been resolved:
wifi: rtw89: avoid to add interface to list twice when SER
If SER L2 occurs during the WoWLAN resume flow, the add interface flow is triggered by ieee80211_reconfig(). However, due to rtw89_wow_resume() return failure, it will cause the add interface flow to be executed again, resulting in a double add list and causing a kernel panic. Therefore, we have added a check to prevent double adding of the list.
