A flaw was found in the Linux kernel. A NULL pointer dereference in the `acpi_ev_address_space_dispatch()` function could allow a local attacker to cause a denial of service (DoS) by triggering a missed execution path. This vulnerability arises from an incomplete check in the Advanced Configuration and Power Interface (ACPI) component.
