Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> ALSA: usb-audio: Avoid potential endless loop in convert_chmap_v3()<br /> <br /> The convert_chmap_v3() has a loop with its increment size of<br /> cs_desc-&gt;wLength, but we forgot to validate cs_desc-&gt;wLength itself,<br /> which may lead to potential endless loop by a malformed descriptor.<br /> <br /> Add a proper size check to abort the loop for plugging the hole.
