CVE-2026-31426

A flaw was found in the Linux kernel's Advanced Configuration and Power Interface ACPI Embedded Controller EC subsystem. During the setup of the EC handler, if a probe deferral occurs on specific hardware, the system fails to properly deallocate resources. This oversight creates a use-after-free...
