CVE-2026-43372

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> net: dsa: microchip: Fix error path in PTP IRQ setup<br /> <br /> If request_threaded_irq() fails during the PTP message IRQ setup, the<br /> newly created IRQ mapping is never disposed. Indeed, the<br /> ksz_ptp_irq_setup()&amp;#39;s error path only frees the mappings that were<br /> successfully set up.<br /> <br /> Dispose the newly created mapping if the associated<br /> request_threaded_irq() fails at setup.
