CVE-2025-21990

This CVE affects the Linux kernel DRM/AMDGPU path. The vulnerability arises when determining GFX12 page table entry (PTE) flags for BOs (backing stores). Specifically, PRT BOs may have no backing store, making bo->tbo.resource NULL. If this NULL is dereferenced, it can lead to a crash or other...
