CVE-2023-31026

Service interruption via Virtual GPU Manager NULL dereference

Published Nov 2, 2023 · Updated Sep 5, 2024

NULL-pointer dereference in NVIDIA vGPU software allows local users to interrupt the Virtual GPU Manager on a hypervisor host. NVIDIA identifies the affected locus only as the vGPU plugin and has not disclosed which input or operation produces the NULL pointer. Exploitation requires local access and high privileges; the bounded result is loss of availability across the privilege boundary, with no reported data disclosure or modification.
