CVE-2025-38130

Privileged kernel Oops via NULL callback dereference

Published Jul 3, 2025 · Updated May 11, 2026

NULL pointer dereference in Linux 6.14 through 6.15.2 allows local users to trigger a kernel Oops during HDMI driver removal. The HDMI audio helper's plugged callback path invokes a NULL function pointer passed by hdmi_remove without first checking fn. Triggering driver removal or device unbind requires root privileges or CAP_SYS_MODULE, and the documented consequence is an Oops rather than data access or modification.
