## Overview

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

mm/damon/reclaim: fix potential memory leak in damon_reclaim_init()

damon_reclaim_init() allocates a memory chunk for ctx with
damon_new_ctx().  When damon_select_ops() fails, ctx is not released,
which will lead to a memory leak.

We should release the ctx with damon_destroy_ctx() when damon_select_ops()
fails to fix the memory leak.

## Affected

- `Linux >= 4d69c3457821100a39fa8c6e0c23ed910bb6c29d < 9d3e9e1e0856f4c905bbb870f16f42ae72477071`
- `Linux >= 4d69c3457821100a39fa8c6e0c23ed910bb6c29d < 700aa4e11a3c4d2a44d06758db431a013d9e1b61`
- `Linux >= 4d69c3457821100a39fa8c6e0c23ed910bb6c29d < 188043c7f4f2bd662f2a55957d684fffa543e600`
- `Linux 5.18`
