DEBIAN-CVE-2026-90047

In the Linux kernel, the following vulnerability has been resolved: drm/xe: Don't hand out the flat CCS storage as usable VRAM getflatccsoffset reads the base of the flat CCS storage from the hardware, scales it by the number of enabled L3 nodes, and rounds the result up to 128K. Everything below...

CVE-2026-90047

This vulnerability affects the Linux kernel's drm/xe driver (Intel Xe GPU driver). The get_flat_ccs_offset() function incorrectly rounds up the flat CCS (Compressed Caching System) storage boundary to 128 KiB instead of rounding down to the allocator's page size, exposing a small region of memory...
