CVE-2025-39859

CVE-2025-39859 : In the Linux kernel, a race condition can cause a use-after-free when the timer watchdog used by ptp_ocp_watchdog is running during devlink deallocation. The flaw occurs because ptp_ocp_detach() only cancels the watchdog if it is pending; if the timer handler is active, timer_del...
