## Overview

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

ASoC: tas2781: bound firmware description string parsing

The TAS2781 firmware parser reads several variable-length description
strings with strlen() before checking that the string terminator is
present inside the firmware blob. A malformed firmware image without a
NUL terminator can therefore make the parser walk past the end of the
firmware buffer before the later size checks run.

Add a small bounded string-length helper and use it for all description
fields that are parsed from the firmware buffer. Keep the existing size
checks for the fixed bytes that follow each string.

## Affected

- `Linux >= 915f5eadebd29ba185ac506766a90120153b7e14 < 3ddb0d3e36507615e5ef010a879357a54870adf5`
- `Linux >= 915f5eadebd29ba185ac506766a90120153b7e14 < 0ec45e80a82785ee147516fdecf5c93707dec119`
- `Linux >= 915f5eadebd29ba185ac506766a90120153b7e14 < 41ae2b7d37c3dd82302167496836cca9f0328374`
- `Linux >= 915f5eadebd29ba185ac506766a90120153b7e14 < e75ef37d83c90b09bedb601624b47e168202b226`
- `Linux >= 915f5eadebd29ba185ac506766a90120153b7e14 < bc889dfcea9294a1eae7f8e2f3573a90764ae4d0`
