Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description An out-of-bounds read issue exists in the drm/amdgpu/vcn4 component when parsing the Indirect Buffer (IB). This occurs because the parsing process does not properly validate bounds, potentially allowing reads beyond the intended memory area.

Recommendations Rewrite the IB parsing to utilize the amdgpu ib get value() function, which implements the necessary bounds checks.
