## Overview

In the Linux kernel, the following vulnerability has been resolved:

net: ethernet: cortina: Ack RX overrun interrupt correctly

The RX overrun interrupt is reported in interrupt status register 4, but
gmac_irq() acknowledges it using the RX descriptor error bit from status
register 0. For GMAC0 this writes the GMAC1 overrun bit, while for GMAC1
the shift leaves no bit in the 32-bit register.

Acknowledge the same per-port RX overrun bit that was detected.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
