CVE-2026-24071 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. It was found that the XPC service offered by the privileged helper of Native Access uses the PID of the connecting client to verify its code signature. This is considered insecure and can be exploited by PID reuse attacks. The connection handler function uses _xpc_connection_get_pid(arg2) as argument for the hasValidSignature function. EPSS estimates a 0.15% chance of exploitation in the next 30 days.
