AI-suggested
A patch is available and should be applied to affected Linux kernel versions. The vendor advisory (Ubuntu USN-7769-1) confirms that this and other kernel security issues have been fixed. Users should update their Linux kernel to a fixed version as per the vendor's security notice to remediate this vulnerability.
Description
A race condition vulnerability in the Linux kernel's coresight subsystem was resolved. The issue involved improper locking (cscfg_csdev_lock) during removal of coresight configurations, potentially causing race conditions when activating and deactivating configurations concurrently on multiple CPUs. This flaw could lead to system instability or crashes. The vulnerability affects multiple specific Linux kernel versions and has been fixed in updated releases.
