UBUNTU-CVE-2026-68268

In the Linux kernel, the following vulnerability has been resolved: drm/xe: Return error on non-migratable faults requiring devmem Non-migratable faults that require devmem incorrectly jump to the 'out' label, which squashes the error code intended to be returned to the upper layers. Fix this by...

UBUNTU-CVE-2026-68383

In the Linux kernel, the following vulnerability has been resolved: drm/xe/guc: Keep scheduler timeline name alive The scheduler keeps a pointer to the timeline name, but q-name is freed with the exec queue while scheduler fences can still reference it. Store the name in struct xegucexecqueue so ...
