A patch is available and should be applied to affected Linux kernel versions. The vendor advisory from Ubuntu confirms that this issue has been fixed in updated kernel releases. Users should update to fixed kernel versions to remediate this vulnerability.
Description
A vulnerability in the Linux kernel's mac80211 WiFi subsystem was resolved by correcting a concurrency issue where a static variable was shared across parallel invocations, potentially causing packet misprocessing. This flaw could lead to packets being incorrectly handled between mesh and 802.3 processing paths. The issue affects multiple specific Linux kernel versions and has a high CVSS score of 8.8. A patch is available to fix this by making the variable automatic, ensuring thread safety.
