CVE-2026-31460 Details
Description
In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: check if ext_caps is valid in BL setup LVDS connectors don't have extended backlight caps so check if the pointer is valid before accessing it. (cherry picked from commit 3f797396d7f4eb9bb6eded184bbc6f033628a6f6)
A vulnerability in the Linux kernel's handling of LVDS connectors has been addressed. LVDS connectors lack extended backlight capabilities, so the kernel now verifies the validity of the pointer to extended capabilities before accessing it. This change prevents potential issues that could arise from accessing invalid memory locations.
