This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

drm/amdgpu: Fix the memory allocation issue in amdgpu_discovery_get_nps_info()

Fix two issues with memory allocation in amdgpu_discovery_get_nps_info()

for mem_ranges:

- Add a check for allocation failure to avoid dereferencing a null

pointer.

- As suggested by Christophe, use kvcalloc() for memory allocation,

which checks for multiplication overflow.

Additionally, assign the output parameters nps_type and range_cnt after

the kvcalloc() call to prevent modifying the output parameters in case

of an error return.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
