AI-suggested
A fix is available and included in updated Linux kernel releases. Users should apply the official Linux kernel security updates that address this and other vulnerabilities as detailed in the Ubuntu security advisory USN-7594-1. The vendor advisory confirms that these updates correct the flaw by changing the reset mechanism to avoid writing to inaccessible registers.
Description
A vulnerability in the Linux kernel's drm/xe/vf driver was resolved that prevented improper attempts by virtual functions (VFs) to trigger a full graphics technology (GT) reset when they lack access to the reset register. Attempts to trigger a reset via debugfs or driver-detected hang conditions could cause warnings and invalid operations. The fix involves sending a specific VF_RESET action instead of writing to an inaccessible register.
