| Vector | AV:A/AC:L/Au:S/C:C/I:C/A:C |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.17.0-rc1+
Description
The Linux kernel contains a use-after-free flaw within the rtw89 core component. Specifically, the issue occurs in the
rtw89 core tx kick off and wait() function when accessing already freed memory associated with skb data. This is a result of a race condition between the waiting and signaling threads during completion processing. The rtw89 core tx kick off and wait() function attempts to access memory that has already been freed by another thread, leading to a potential system crash or unpredictable behavior. The vulnerable function is called during scan completion and involves interactions with the skbuff head cache.Recommendations
Update to Linux kernel version 6.17.0-rc1+ or later.
