Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> net: asix: add proper error handling of usb read errors<br /> <br /> Syzbot once again hit uninit value in asix driver. The problem still the<br /> same -- asix_read_cmd() reads less bytes, than was requested by caller.<br /> <br /> Since all read requests are performed via asix_read_cmd() let&amp;#39;s catch<br /> usb related error there and add __must_check notation to be sure all<br /> callers actually check return value.<br /> <br /> So, this patch adds sanity check inside asix_read_cmd(), that simply<br /> checks if bytes read are not less, than was requested and adds missing<br /> error handling of asix_read_cmd() all across the driver code.
