Description
From https://gitlab.khronos.org/vulkan/vulkan/-/merge_requests/8088/diffs
Need to update the the static and GPU-AV checks to not allow any `OpCooperativeMatrix*` Load/Stores from accessing a null descriptor
` VUID-RuntimeSpirv-OpCooperativeMatrix-12379` (added in 1.3.345)
Contributor guide
Research direction
Review the linked Vulkan merge request diff and locate the existing static and GPU-AV handling for OpCooperativeMatrix Load/Store operations. Trace how descriptor validity is checked, then verify that null descriptor accesses are rejected under VUID-RuntimeSpirv-OpCooperativeMatrix-12379 for both check paths.
