## Overview

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

orangefs: Fix kmemleak in orangefs_{kernel,client}_debug_init()

When insert and remove the orangefs module, there are memory leaked
as below:

unreferenced object 0xffff88816b0cc000 (size 2048):
  comm "insmod", pid 783, jiffies 4294813439 (age 65.512s)
  hex dump (first 32 bytes):

    [<00000000f11c03c7>] entry_SYSCALL_64_after_hwframe+0x46/0xb0

Use the golbal variable as the buffer rather than dynamic allocate to
slove the problem.

## Affected

- `linux_kernel >= 4.6, < 5.4.229`
- `linux_kernel >= 5.5, < 5.10.163`
- `linux_kernel >= 5.11, < 5.15.86`
- `linux_kernel >= 5.16, < 6.0.16`
- `linux_kernel >= 6.1, < 6.1.2`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.1.2`
