## Overview

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

RDMA/srpt: Do not register event handler until srpt device is fully setup

Upon rare occasions, KASAN reports a use-after-free Write
in srpt_refresh_port().

This seems to be because an event handler is registered before the
srpt device is fully setup and a race condition upon error may leave a
partially setup event handler in place.

Instead, only register the event handler after srpt device initialization
is complete.

## Affected

- `linux_kernel >= 3.3, < 5.10.214`
- `linux_kernel >= 5.11, < 5.15.153`
- `linux_kernel >= 5.16, < 6.1.83`
- `linux_kernel >= 6.2, < 6.6.23`
- `linux_kernel >= 6.7, < 6.7.11`
- `linux_kernel >= 6.8, < 6.8.2`
- `debian_linux = 10.0`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.8.2`
