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...
