## Overview

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

kobject_uevent: Fix OOB access within zap_modalias_env()

zap_modalias_env() wrongly calculates size of memory block to move, so
will cause OOB memory access issue if variable MODALIAS is not the last
one within its @env parameter, fixed by correcting size to memmove.

## Affected

- `linux_kernel >= 4.15.1, < 4.19.320`
- `linux_kernel >= 4.20, < 5.4.282`
- `linux_kernel >= 5.5, < 5.10.224`
- `linux_kernel >= 5.11, < 5.15.165`
- `linux_kernel >= 5.16, < 6.1.103`
- `linux_kernel >= 6.2, < 6.6.44`
- `linux_kernel >= 6.7, < 6.10.3`
- `linux_kernel = 4.15`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.10.3`
