Description OSIDB Bzimport 2026-08-10 12:31:51 UTC
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.
