CVE-2026-46146

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.
