AI-suggested

The vulnerability has been fixed in the Linux kernel versions identified by commits b0e3f019e461ac42e45aa3ec1216cefaca2f4a8b and 708f9d43d6a2eb9c6b83fe62af628de9dffd9314. Users should update to these fixed versions or later to remediate the issue.

Description

A race condition vulnerability in the Linux kernel's wifi cfg80211 IBSS join event handling was fixed. The issue involved a delayed lookup of the BSS entry after joining an IBSS, which could lead to warnings due to the BSS entry being removed by a concurrent scan. The fix involves performing the BSS entry lookup early and maintaining a reference to it to prevent race conditions.
