CVE-2026-5072 ptp: Potential Denial of Service via PTP Interval Shift

A bitwise shift vulnerability in Zephyr's PTP subsystem allows a remote attacker to cause undefined behavior and potential system crashes. An attacker sends a crafted PTPMSGMANAGEMENT message to set an unvalidated negative logannounceinterval value in the port's data set. When a subsequent...

SUSE CVE-2026-43447

In the Linux kernel, the following vulnerability has been resolved: iavf: fix PTP use-after-free during reset Commit 7c01dbfc8a1c5f "iavf: periodically cache PHC time" introduced a worker to cache PHC time, but failed to stop it during reset or disable. This creates a race condition where...

CVE-2026-43372

A flaw was found in the Linux kernel's Microchip DSA Distributed Switch Architecture driver. During the setup of a PTP Precision Time Protocol interrupt, an error can occur where system resources are not properly released. This resource leak could allow a local attacker to cause a denial of servi...

CVE-2026-43447

A flaw was found in the Linux kernel's iavf driver. A race condition exists where the Precision Time Protocol PTP worker attempts to access adapter resources that have already been freed during a reset or disable operation. This use-after-free vulnerability can lead to a system crash, resulting i...
