Detailsinfo

A vulnerability was found in Linux Kernel up to 6.12.105/6.18.46/7.1.10. It has been classified as very critical. Affected is some unknown processing of the component drm xe. The manipulation with an unknown input leads to a allocation of resources vulnerability. CWE is classifying the issue as CWE-770. The product allocates a reusable resource or group of resources on behalf of an actor without imposing any restrictions on the size or number of resources that can be allocated, in violation of the intended security policy for that actor. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: drm/xe: Fix DPT allocation paths. Remove the fallback for VRAM to system memory, I tested it and that doesn't work at all, only a black screen with pipe fault errors were observed. On systems with media GT, extra latency is added when accessing stolen memory when the GT is in MC6. Since we additionally aren't counting how much memory is used for stolen and we could in theory fill up the entire stolen area with DPT's, avoid using stolen and only use the default memory region. Using stolen may also result in random system hangs under load. (cherry picked from commit a196406a3831291598fe8e73245914f7acffdfe0)
