cve 2025 68190

CVE-2025-68190 is a kernel vulnerability in the AMDGPU Atom interpreter within the Linux kernel's AMDGPU driver. The issue involves a missing allocation check in the amdgpu_atom_execute_table_locked function, which can result in a NULL workspace pointer while its size field remains non-zero. This condition leads to a deterministic NULL-dereference that can crash the kernel. The vulnerability has been patched in upstream stable trees. Discussions on WindowsForum.com cover the technical details of the flaw, the affected driver component, and the fix applied to address the NULL pointer dereference. The tag is relevant for users and administrators tracking Linux kernel security updates, particularly those using AMD graphics hardware.
