CVE-2026-31396

A flaw was found in the Linux kernel's Media Access Controller MACB Ethernet driver and Precision Time Protocol PTP clock subsystem. A local attacker could exploit a use-after-free vulnerability by accessing the PTP clock via the gettsinfo ethtool call after the PTP clock has been deallocated. Th...

CVE-2026-31396

Summary: CVE-2026-31396 affects the Linux kernel’s net/macb and PTP clock subsystem. The root cause is a use-after-free in ptp_clock_index() when the PTP clock is accessed via get_ts_info while the interface’s PTP clock object has been deregistered. This allows a local attacker to trigger a crash...

PT-2026-30179

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.1.164+ Description The Linux kernel contained a use-after-free issue in the networking subsystem related to the macb driver and the PTP Precision Time Protocol clock. Specifically, the PTP clock could be access...

The vulnerability of the ptp_clock_register() function in the drivers/ptp/ptp_clock.c module of the Linux operating system’s PTP clock support driver allows a hacker to cause a service failure.

The vulnerability of the ptpclockregister function in the drivers/ptp/ptpclock.c module of the Linux operating system’s time support driver lies in the execution of operations outside of the buffer in memory. Exploiting this vulnerability could allow a attacker to cause a service failure...
