## Overview

A vulnerability was reported in the Open vSwitch sub-component in the Linux Kernel. The flaw occurs when a recursive operation of code push recursively calls into the code block. The OVS module does not validate the stack depth, pushing too many frames and causing a stack overflow. As a result, this can lead to a crash or other related issues.

## Affected

- `kernel (all versions)`
- `kernel (all versions)`
- `kernel (all versions)`
- `kernel-rt (all versions)`
- `kernel`
- `kernel`
- `kernel-rt`
- `kernel (all versions)`
- `kernel-rt (all versions)`
- `kernel-rt (all versions)`

## Remediation

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

### Workarounds

To mitigate this issue, prevent module openvswitch from being loaded. Please see https://access.redhat.com/solutions/41278 for how to blacklist a kernel module to prevent it from loading automatically.
