Vulnerability from fkie_nvd - Published: 2026-07-19 16:17 - Updated: 2026-09-02 21:10
Severity
5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Summary
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/
