CVE-2026-98855

A flaw was found in the Linux kernel's Device Tree overlay subsystem. When an error occurs while adding a property to a device tree overlay changeset, the allocated property is freed during error cleanup but remains tracked, leading to a second release (double-free) when the overlay node is torn down. A local user could exploit this vulnerability to trigger memory corruption, potentially leading to a Denial of Service (DoS) or privilege escalation.
