Descriptions
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.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: net/usb: kalmia: No pasar act_len en la ruta de error usb_bulk_msg syzbot informó que act_len en kalmia_send_init_packet() no está inicializado al pasarlo a la primera ruta de error usb_bulk_msg. Jiri Pirko señaló que no tiene sentido pasarlo en la ruta de error y que el valor que se imprimiría en la segunda ruta de error sería el valor de act_len de la primera llamada a usb_bulk_msg.[1] Con esto en mente, simplemente no pasemos act_len a las rutas de error usb_bulk_msg. 1: https://lore.kernel.org/lkml/Y9pY61y1nwTuzMOa@nanopsycho/
