CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's Adreno graphics driver, specifically in the handling of user space queries related to Unified Bandwidth Compression (UBWC) parameters for the a2xx-a4xx GPU generations. An attacker could exploit this flaw to trigger a NULL pointer dereference, potentially leading to a crash of the affected system. Organizations utilizing Linux systems with these specific Adreno GPU models should prioritize applying the patch to mitigate the risk of service disruption.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: drm/msm/adreno: fix userspace-triggered crash on a2xx-a4xx Before a5xx Adreno driver will not try fetching UBWC params (because those generations didn't support UBWC anyway), however it's still possible to query UBWC-related params from the userspace, triggering possible NULL pointer dereference. Check for UBWC config in adreno_get_param() and return sane defaults if there is none. Patchwork: https://patchwork.freedesktop.org/patch/717778/
