CVE-2023-25071

Local denial of service via NULL pointer dereference

Published Nov 14, 2023 · Updated Aug 30, 2024

NULL pointer dereference in Intel Arc & Iris Xe Graphics Windows Drivers before 31.0.101.4255 allows authenticated users local denial of service. The specific driver code path and operation that dereferences a null pointer are not disclosed in Intel's advisory. Local authenticated access is required, and the bounded consequence is interruption of graphics-driver or host availability rather than data disclosure or modification.
