A flaw was found in the Linux kernel's Advanced Configuration and Power Interface (ACPI) APEI Generic Hardware Error Source (GHES) component. Incorrect length accounting in the ghes_handle_arm_hw_error() function can lead to the parser reading beyond the allocated memory section. This out-of-bounds read could potentially result in a denial of service or information disclosure.
