Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description A flaw exists in the ALSA usb-audio component within the convert chmap v3() function. The function contains a loop that uses the cs desc->wLength variable to determine the increment size. Because the cs desc->wLength value is not validated, a malformed descriptor can trigger an endless loop.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
