CVE-2026-46204 Details
Description
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/vcn4: Prevent OOB reads when parsing IB Rewrite the IB parsing to use amdgpu_ib_get_value() which handles the bounds checks.
A vulnerability allowing out-of-bounds reads has been addressed in the Linux kernel's AMDGPU video coding engine version 4.0. This issue arose during the parsing of instruction buffers, where improper bounds checks could lead to reading data outside the intended limits. The vulnerability has been mitigated by rewriting the instruction buffer parsing to utilize a function that properly handles bounds verification.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been addressed. The specific commit containing the fix is available in the Linux kernel stable tree.
