CVE-2026-63837

The CVE affects the Linux kernel ENA PHC path. In ena_phc_gettimex64, the output timestamp was written to the user via the PTP ioctl regardless of whether ena_com_phc_get_timestamp() succeeded. If an error occurs (e.g., PHC disabled or blocked), the timestamp could contain uninitialized memory or...

CVE-2026-53222

In the Linux kernel, CVE-2026-53222 relates to the ptp: ocp driver. The root cause was use-after-free during driver removal caused by freeing resources in ptp_ocp_detach() before ptp_clock_unregister(), after a change that disables events via ptp_disable_all_events(). The fix changes the free/unr...

PT-2026-52317

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A use-after-free issue exists during driver removal in the Precision Time Protocol PTP OCP implementation. The ptp ocp detach function frees pin resources before calling ptp clock...
