In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
drm\/xe: Fix DPT allocation paths.<\/p>\n
Remove the fallback for VRAM to system memory, I tested it and that
\ndoesn’t work at all, only a black screen with pipe fault errors were
\nobserved.<\/p>\n
On systems with media GT, extra latency is added when accessing stolen
\nmemory when the GT is in MC6. Since we additionally aren’t counting how
\nmuch memory is used for stolen and we could in theory fill up the
\nentire stolen area with DPT’s, avoid using stolen and only use the
\ndefault memory region.<\/p>\n
Using stolen may also result in random system hangs under load.<\/p>\n
