Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> net/usb: kalmia: Don&amp;#39;t pass act_len in usb_bulk_msg error path<br /> <br /> syzbot reported that act_len in kalmia_send_init_packet() is<br /> uninitialized when passing it to the first usb_bulk_msg error path. Jiri<br /> Pirko noted that it&amp;#39;s pointless to pass it in the error path, and that<br /> the value that would be printed in the second error path would be the<br /> value of act_len from the first call to usb_bulk_msg.[1]<br /> <br /> With this in mind, let&amp;#39;s just not pass act_len to the usb_bulk_msg error<br /> paths.<br /> <br /> 1: https://lore.kernel.org/lkml/Y9pY61y1nwTuzMOa@nanopsycho/
