## Overview

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

ASoC: amd: acp-sdw-sof: Bound DAI link iteration

create_sdw_dailinks() walks sof_dais until it finds an entry with
initialised cleared, but sof_dais is allocated with exactly num_ends
entries. If all entries are initialised, the loop reads past the end of
the array.

Pass the allocated entry count to create_sdw_dailinks() and stop before
reading past the array.

## Affected

- `Linux >= 6d8348ddc56ed43ba39d1e8adda13299201f32ed < 0a5ff4000dd7a390139dd7823fef1de4963e490a`
- `Linux >= 6d8348ddc56ed43ba39d1e8adda13299201f32ed < 9e82497138abea7d5c6e65015663d907fbcbf6b4`
- `Linux >= 6d8348ddc56ed43ba39d1e8adda13299201f32ed < 86a64c049873fe4d4a6a378e27a333ab5631c4b2`
- `Linux >= 6d8348ddc56ed43ba39d1e8adda13299201f32ed < 4d992e63f52d58f52b724606c60ae7b37a1c582f`
- `Linux 6.12`
