CVE-2026-53307
Description
A flaw was found in the Linux kernel. The pinctrl: pinconf-generic subsystem does not properly validate the 'pinmux' property. An attacker could provide an empty 'pinmux' property, which would cause the system to crash due to invalid memory access. This could lead to a denial of service.
