## Overview

A flaw was found in unrestricted eBPF usage by the BPF_BTF_LOAD, leading to a possible out-of-bounds memory write in the Linux kernel’s BPF subsystem due to the way a user loads BTF. This flaw allows a local user to crash or escalate their privileges on the system.

## Affected

- `linux_kernel >= 5.10, < 5.15.37`
- `linux_kernel >= 5.16, < 5.16.11`
- `fedora = 34`
- `fedora = 35`
- `h300e_firmware`
- `h300s_firmware`
- `h410c_firmware`
- `h410s_firmware`
- `h500e_firmware`
- `h500s_firmware`
- `h700e_firmware`
- `h700s_firmware`

## Remediation

Upgrade past the affected range:

- `linux_kernel 5.16.11`
