NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-uek-modules-wireless package and not the kernel-uek-modules-wireless package as distributed by Oracle. See How to fix? for Oracle:9 relevant fixed versions and status.

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

drm/amdgpu: Use kvfree instead of kfree in amdgpu_gmc_get_nps_memranges()

amdgpu_discovery_get_nps_info() internally allocates memory for ranges using kvcalloc(), which may use vmalloc() for large allocation. Using kfree() to release vmalloc memory will lead to a memory corruption.

Use kvfree() to safely handle both kmalloc and vmalloc allocations.

Compile tested only. Issue found using a prototype static analysis tool and code review.
