Severity ?
5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: drm/xe: Don't overmap identity VRAM mapping Overmapping the identity VRAM mapping is triggering hardware bugs on certain platforms. Use 2M pages for the last unaligned (to 1G) VRAM chunk. v2: - Always use 2M pages for last chunk (Fei Yang) - break loop when 2M pages are used - Add assert for usable_size being 2M aligned v3: - Fix checkpatch
