Description
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/vcn3: Prevent OOB reads when parsing dec msg Check bounds against the end of the BO whenever we access the msg.
A vulnerability in the Linux kernel's AMDGPU VCN3 decoder can lead to out-of-bounds (OOB) reads. This issue arises when the decoder parses message data without properly checking the bounds against the end of the buffer object (BO). The vulnerability is present in the Linux kernel stable tree.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been patched. Instructions for downloading the updated kernel can be found on the official Linux kernel website.
