CVE-2024-49939

8.8 · HIGH
Published Oct 21, 2024 linux EPSS 0.34% (27th pctl)

Overview

CVE-2024-49939 is a high-severity vulnerability affecting linux linux_kernel. It was published on October 21, 2024 and has a CVSS 3.1 base score of 8.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.8, rated HIGH. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical Description

In 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.

list_add double add: new=ffff99d6992e2010, prev=ffff99d6992e2010, next=ffff99d695302628.
