## Overview

An issue was discovered in the Linux kernel before 6.0.11. Missing validation of the number of channels in drivers/net/wireless/microchip/wilc1000/cfg80211.c in the WILC1000 wireless driver can trigger a heap-based buffer overflow when copying the list of operating channels from Wi-Fi management frames.

## Affected

- `linux_kernel >= 4.2, < 5.10.157`
- `linux_kernel >= 5.11, < 5.15.81`
- `linux_kernel >= 5.16, < 6.0.11`
- `debian_linux = 10.0`
- `h410c_firmware`
- `h300s_firmware`
- `h500s_firmware`
- `h700s_firmware`
- `h410s_firmware`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.0.11`
