2DescriptionCVE.org
Software installed and run as a non-privileged user may conduct improper GPU system calls to gain write permission to read-only wrapped user-mode memory.
This is caused by improper handling of the memory protections for the user-mode wrapped memory resource.
AnalysisAI
Improper GPU system call handling in the DDK allows non-privileged users to bypass memory protections on user-mode wrapped memory regions and gain unauthorized write access. An attacker with local access could exploit this to modify read-only memory structures, potentially compromising system integrity or escalating privileges. No patch is currently available for this medium-severity vulnerability.
