## Overview

Four memory leaks in the nfp_flower_spawn_phy_reprs() function in drivers/net/ethernet/netronome/nfp/flower/main.c in the Linux kernel before 5.3.4 allow attackers to cause a denial of service (memory consumption), aka CID-8572cea1461a.

## Affected

- `linux_kernel < 5.3.4`
- `leap = 15.1`

## Remediation

Upgrade past the affected range:
