CVE-2023-53250

Kernel panic via uninitialized DMI list deletion

Published Sep 15, 2025 · Updated Sep 15, 2025

NULL pointer dereference in the Linux kernel dmi-sysfs component allows local users to trigger a kernel panic during module initialization. The dmi_sysfs_register_handle error path calls kobject_put(), whose release callback deletes entry->list before list_add_tail() initializes and links it. Low-privileged local access is required, and exploitation interrupts the entire host without reported data disclosure or modification.
