CVE-2024-42228 is an uninitialized-variable vulnerability in the Linux kernel DRM AMDGPU driver. The driver can use the size value before initialization when invoking amdgpu_vce_cs_reloc, including through the 0x03000001 case. The corrective change initializes size before this call; notes accompanying the fix indicate that fully improved handling would require a separate 0xffffffff value.
