CVE-2024-27042

In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: Fix potential out-of-bounds access in
‘amdgpu_discovery_reg_base_init()’ The issue arises when the array
‘adev->vcn.vcn_config’ is accessed before checking if the index
‘adev->vcn.num_vcn_inst’ is within the bounds of the array. The fix
involves moving the bounds check before the array access. This ensures that
‘adev->vcn.num_vcn_inst’ is within the bounds of the array before it is
used as an index. Fixes the below:
drivers/gpu/drm/amd/amdgpu/amdgpu_discovery.c:1289
amdgpu_discovery_reg_base_init() error: testing array offset
‘adev->vcn.num_vcn_inst’ after use.
