CVE-2026-45853

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

Description A memory corruption issue exists in the drm/amdgpu component. The function amdgpu discovery get nps info() allocates memory for ranges using kvcalloc(), which may utilize vmalloc() for large allocations. The use of kfree() to release memory allocated via vmalloc() leads to memory corruption. This is addressed by using kvfree() in the amdgpu gmc get nps memranges() function to safely handle both kmalloc and vmalloc allocations.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
