CVE Details

Release Date:	2024-05-01
Impact:	Moderate	What is this?

Description

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