## Overview

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

safesetid: check size of policy writes

syzbot attempts to write a buffer with a large size to a sysfs entry
with writes handled by handle_policy_update(), triggering a warning
in kmalloc.

Check the size specified for write buffers before allocating.

[PM: subject tweak]

## Affected

- `linux_kernel >= 5.1, < 5.10.235`
- `linux_kernel >= 5.11, < 5.15.179`
- `linux_kernel >= 5.16, < 6.1.129`
- `linux_kernel >= 6.2, < 6.6.78`
- `linux_kernel >= 6.7, < 6.12.14`
- `linux_kernel >= 6.13, < 6.13.3`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.13.3`
