CVE-2026-53222

The CVE-2026-53222 entry concerns the Linux kernel PTP subsystem (ptp: ocp). The vulnerability arises from an incorrect order of resource freeing and unregistration during driver removal: ptp_ocp_detach() freed resources before ptp_clock_unregister(), creating a use-after-free condition. The fix ...
