Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A flaw exists in the Linux kernel's ALSA subsystem, specifically within the scarlett2 module. A logic error in the
scarlett2 usb get config() function’s endianness conversion code can lead to buffer overflows when the count variable is greater than 1. The issue arises because the code incorrectly checks the total buffer size (size) instead of the element size (config item->size), resulting in out-of-bounds memory access during the endianness conversion loop. The loop attempts to access count * 2 bytes, potentially exceeding the allocated buffer size of size bytes.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
