CVE-2026-43372
Description
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.
