Summary
In the Linux kernel, the ASoC tas2781 driver has an out-of-bounds read vulnerability when parsing firmware description strings. The parser uses strlen() without checking if the NUL terminator is present in the firmware buffer, which can cause reads past the end of the buffer with a malformed firmware image.
Risk Assessment
Possible kernel memory disclosure or system crash due to buffer overread.
Recommendation
Install the Linux kernel patch that adds a bounded string-length helper and uses it for all description fields.
Original NVD description (English source)
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.
