In the Linux kernel, the following vulnerability has been resolved:
net/usb: kalmia: Don’t pass act_len in usb_bulk_msg error path
syzbot reported that act_len in kalmia_send_init_packet() is
uninitialized when passing it to the first usb_bulk_msg error path. Jiri
Pirko noted that it’s pointless to pass it in the error path, and that
the value that would be printed in the second error path would be the
value of act_len from the first call to usb_bulk_msg.[1]
With this in mind, let’s just not pass act_len to the usb_bulk_msg error
paths.
