Description OSIDB Bzimport 2025-06-18 12:01:57 UTC 
In the Linux kernel, the following vulnerability has been resolved:

drm/i915/ttm: don't leak the ccs state

The kernel only manages the ccs state with lmem-only objects, however
the kernel should still take care not to leak the CCS state from the
previous user.

(cherry picked from commit 353819d85f87be46aeb9c1dd929d445a006fc6ec)
