## Overview

io_uring use work_flags to determine which identity need to grab from the calling process to make sure it is consistent with the calling process when executing IORING_OP. Some operations are missing some types, which can lead to incorrect reference counts which can then lead to a double free. We recommend upgrading the kernel past commit df3f3bb5059d20ef094d6b2f0256c4bf4127a859

## Affected

- `h300s_firmware`
- `h500s_firmware`
- `h700s_firmware`
- `h410s_firmware`
- `h410c_firmware`
- `linux_kernel < 5.10.125`
- `linux_kernel >= 5.11, < 5.12`

## Remediation

Upgrade past the affected range:

- `linux_kernel 5.12`
