## Overview

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

net/mlx5: HWS, Handle destroying table that has a miss table

If a table has a miss table that was created by
'mlx5hws_table_set_default_miss' API function, its miss_tbl
keeps the table that points to it in a list.
If such table is deleted, we need to also remove it from the
miss_tbl list, otherwise the node in miss_tbl list will contain
garbage.

## Affected

- `Linux >= 9fc43b5e3933a7e5924ba83d7561399d439de5bb < 6efdc212627cecf33b594256ae4460b4c52a126a`
- `Linux >= 9fc43b5e3933a7e5924ba83d7561399d439de5bb < 60e9e82f162ab7399373ff2185119289e4f6dc06`
- `Linux 6.14`
