CVE-2025-23162
Estado: AnalizadaMedia (5.5)—
In the Linux kernel, the following vulnerability has been resolved:
drm/xe/vf: Don't try to trigger a full GT reset if VF
VFs don't have access to the GDRST(0x941c) register that driver uses to reset a GT. Attempt to trigger a reset using debugfs:
$ cat /sys/kernel/debug/dri/0000:00:02.1/gt0/force_reset
or due to a hang condition detected by the driver leads to:
Fix that by sending H2G VF_RESET(0x5507) action instead.
