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.

Affected configurations

• linux linux kernel (>= 6.6.119 < 6.6.130) • linux linux kernel (>= 6.12.61 < 6.12.78) • linux linux kernel (>= 6.17.11 < 6.18) • linux linux kernel (>= 6.18.1 < 6.18.19) • linux linux kernel (>= 6.19 < 6.19.9) • linux linux kernel 6.18 • linux linux kernel 7.0
