drm/amdgpu/vce1: Fix VCE 1 firmware size and offsets

Assigner: Linux
Reserved: 19.07.2026 Published: 25.07.2026 Updated: 25.07.2026

In the Linux kernel, the following vulnerability has been resolved:

drm/amdgpu/vce1: Fix VCE 1 firmware size and offsets

The VCPU BO contains the actual FW at an offset, but it was not calculated into the VCPU BO size. Subtract this from the FW size to make sure there is no out of bounds access.

Make sure the stack and data offsets are aligned to the 32K TLB size.

Check that the FW microcode actually fits in the space that is reserved for it.
