Linux Kernel up to 6.18.43/7.1.5/7.2-rc3 drm/xe/vm out-of-bounds

CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability was found in Linux Kernel up to 6.18.43/7.1.5/7.2-rc3. It has been rated as very critical. This issue affects an unknown functionality of the file drm/xe/vm. The manipulation with an unknown input leads to a out-of-bounds vulnerability. Using CWE to declare the problem leads to CWE-125. The product reads data past the end, or before the beginning, of the intended buffer. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: drm/xe/vm: Fix BO prefetch with CONSULT_MEM_ADVISE_PREF_LOC When prefetch region is DRM_XE_CONSULT_MEM_ADVISE_PREF_LOC for a BO VMA, the code used it as an index into region_to_mem_type[], causing an out-of-bounds access since the value is -1. Resolve the preferred location for BO VMAs directly: local VRAM on dGFX (using the BO's tile placement) or system memory on iGPU. Discovered using AI-assisted static analysis confirmed by Intel Product Security. v2: -Fix null dereference (cherry picked from commit d9a4906ac03be9f6ed3f3b45c56c866b867fd75b)
