CVE-2024-58011

Kernel crash via NULL ACPI companion dereference

Published Feb 27, 2025 · Updated Sep 8, 2026

NULL pointer dereference in Linux 5.14 and Siemens MFP controllers V3.1.6 and later allows local users to crash the kernel through sysfs. skl_int3472_get_acpi_buffer() dereferences an ACPI device after a bound device's firmware node yields no ACPI companion, without first checking for NULL. Exploitation requires local low-privilege access and manual binding of an int3472 driver to another I2C or platform device; the reported impact is a kernel crash.
