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 ...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ptp: Ensure that info-enable callback is always set. The ioctl and sysfs handlers call the -enable callback unconditionally. Not all drivers implement this callback, resulting in NULL dereferencing. Examples of affected drivers:...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: Networking: DSA: Microchip: Fixed the error path in PTP IRQ setup. If the requestthreadedirq function fails during the PTP message IRQ setup, the newly created IRQ mapping is never disposed of. In fact, the error path in...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: net/mlx5e: Track xmit submissions to PTP WQ after populating the metadata map. Ensure that the skb is available in the metadata mapping to skbs before tracking the metadata index to detect undelivered CQEs. If the metadata ind...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: - ice: fixed the issue where calls to PF PTP cleanup iceptpcleanuppf function and the ‘pslock’ mutex deinitialization were missed during error paths involving driver removal. The cleanup process for releasing PTP resources...
