CVE-2026-45853
Summary

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.
