CVE-2022-50037

Estado: AnalizadaMedia (5.5)—

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)
