CVE-2026-46199 Details
Description
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/vcn4: Prevent OOB reads when parsing dec msg Check bounds against the end of the BO whenever we access the msg.
A vulnerability allowing out-of-bounds reads has been identified in the Linux kernel's AMDGPU video codec decoder, specifically in version 4.0 of the VCN (Video Codec Next) decoder. The issue arises when the decoder parses message data, as it fails to properly check the bounds of the buffer object, potentially leading to unauthorized memory access.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been patched. The specific commit addressing this issue is available in the Linux kernel stable tree.
