In the Linux kernel, the following vulnerability has been resolved: net: dsa: microchip: Fix error path in PTP IRQ setup If request_threaded_irq() fails during the PTP message IRQ setup, the newly created IRQ mapping is never disposed. Indeed, the ksz_ptp_irq_setup()'s error path only frees the mappings that were successfully set up. Dispose the newly created mapping if the associated request_threaded_irq() fails at setup.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

(CVE-2026-43372)

Note that Nessus relies on the presence of the package as reported by the vendor.
