usbip: validate number_of_packets in usbip_pack_ret_submit()
Overview
Description
In the Linux kernel, the following vulnerability has been resolved: usbip: validate number_of_packets in usbip_pack_ret_submit() When a USB/IP client receives a RET_SUBMIT response, usbip_pack_ret_submit() unconditionally overwrites urb->number_of_packets from the network PDU. This value is subsequently used as the loop bound in usbip_recv_iso() and usbip_pad_iso() to iterate over urb->iso_frame_desc[], a flexible array whose size was fixed at URB allocation time based on the *original* number_of_packets from the CMD_SUBMIT. A malicious USB/IP server can set number_of_packets in the response to a value larger than what was originally submitted, causing a heap out-of-bounds write when usbip_recv_iso() writes to urb->iso_frame_desc[i] beyond the allocated region. KASAN confirmed this with kernel 7.0.0-rc5: BUG: KASAN: slab-out-of-bounds in usbip_recv_iso+0x46a/0x640 Write of size 4 at addr ffff888106351d40 by task vhci_rx/69 The buggy address is located 0 bytes to the right of allocated 320-byte region [ffff888106351c00, ffff888106351d40) The server side (stub_rx.c) and gadget side (vudc_rx.c) already validate number_of_packets in the CMD_SUBMIT path since commits c6688ef9f297 ("usbip: fix stub_rx: harden CMD_SUBMIT path to handle malicious input") and b78d830f0049 ("usbip: fix vudc_rx: harden CMD_SUBMIT path to handle malicious input"). The server side validates against USBIP_MAX_ISO_PACKETS because no URB exists yet at that point. On the client side we have the original URB, so we can use the tighter bound: the response must not exceed the original number_of_packets. This mirrors the existing validation of actual_length against transfer_buffer_length in usbip_recv_xbuff(), which checks the response value against the original allocation size. Kelvin Mbogo's series ("usb: usbip: fix integer overflow in usbip_recv_iso()", v2) hardens the receive-side functions themselves; this patch complements that work by catching the bad value at its source -- in usbip_pack_ret_submit() before the overwrite -- and using the tighter per-URB allocation bound rather than the global USBIP_MAX_ISO_PACKETS limit. Fix this by checking rpdu->number_of_packets against urb->number_of_packets in usbip_pack_ret_submit() before the overwrite. On violation, clamp to zero so that usbip_recv_iso() and usbip_pad_iso() safely return early.

Solution
Apply kernel patches to validate packet counts in USB/IP responses to prevent memory corruption.
- Update the Linux kernel to a patched version.
- Ensure USB/IP client validates packet counts.
- Apply Kelvin Mbogo's series for hardening.
- Validate packet counts before overwriting.

Action Type Old Value New Value Added Translation Title: Linux Kernel, Description: En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta: usbip: validar number_of_packets en usbip_pack_ret_submit() Cuando un cliente USB/IP recibe una respuesta RET_SUBMIT, usbip_pack_ret_submit() sobrescribe incondicionalmente urb -> number_of_packets del PDU de red. Este valor se utiliza posteriormente como límite de bucle en usbip_recv_iso() y usbip_pad_iso() para iterar sobre urb -> iso_frame_desc[], un array flexible cuyo tamaño se fijó en el momento de la asignación del URB basándose en el number_of_packets original del CMD_SUBMIT. Un servidor USB/IP malicioso puede establecer number_of_packets en la respuesta a un valor mayor que el que se envió originalmente, causando una escritura fuera de límites en el heap cuando usbip_recv_iso() escribe en urb -> iso_frame_desc[i] más allá de la región asignada. KASAN confirmó esto con el kernel 7.0.0-rc5: BUG: KASAN: slab-out-of-bounds in usbip_recv_iso+0x46a/0x640 Write of size 4 at addr ffff888106351d40 by task vhci_rx/69 The buggy address is located 0 bytes to the right of allocated 320-byte region [ffff888106351c00, ffff888106351d40) El lado del servidor (stub_rx.c) y el lado del gadget (vudc_rx.c) ya validan number_of_packets en la ruta CMD_SUBMIT desde los commits c6688ef9f297 (’usbip: fix stub_rx: harden CMD_SUBMIT path to handle malicious input’) y b78d830f0049 (’usbip: fix vudc_rx: harden CMD_SUBMIT path to handle malicious input’). El lado del servidor valida contra USBIP_MAX_ISO_PACKETS porque aún no existe un URB en ese punto. En el lado del cliente tenemos el URB original, por lo que podemos usar el límite más estricto: la respuesta no debe exceder el number_of_packets original. Esto refleja la validación existente de actual_length contra transfer_buffer_length en usbip_recv_xbuff(), que verifica el valor de respuesta contra el tamaño de asignación original. La serie de Kelvin Mbogo (’usb: usbip: fix desbordamiento de entero en usbip_recv_iso()’, v2) refuerza las propias funciones del lado de recepción; este parche complementa ese trabajo al detectar el valor incorrecto en su origen - - en usbip_pack_ret_submit() antes de la sobrescritura - - y utilizando el límite de asignación por URB más estricto en lugar del límite global USBIP_MAX_ISO_PACKETS. Solucione esto verificando rpdu -> number_of_packets contra urb -> number_of_packets en usbip_pack_ret_submit() antes de la sobrescritura. En caso de violación, se ajusta a cero para que usbip_recv_iso() y usbip_pad_iso() regresen de forma segura y anticipada. -

Action Type Old Value New Value Added Description In the Linux kernel, the following vulnerability has been resolved: usbip: validate number_of_packets in usbip_pack_ret_submit() When a USB/IP client receives a RET_SUBMIT response, usbip_pack_ret_submit() unconditionally overwrites urb->number_of_packets from the network PDU. This value is subsequently used as the loop bound in usbip_recv_iso() and usbip_pad_iso() to iterate over urb->iso_frame_desc[], a flexible array whose size was fixed at URB allocation time based on the *original* number_of_packets from the CMD_SUBMIT. A malicious USB/IP server can set number_of_packets in the response to a value larger than what was originally submitted, causing a heap out-of-bounds write when usbip_recv_iso() writes to urb->iso_frame_desc[i] beyond the allocated region. KASAN confirmed this with kernel 7.0.0-rc5: BUG: KASAN: slab-out-of-bounds in usbip_recv_iso+0x46a/0x640 Write of size 4 at addr ffff888106351d40 by task vhci_rx/69 The buggy address is located 0 bytes to the right of allocated 320-byte region [ffff888106351c00, ffff888106351d40) The server side (stub_rx.c) and gadget side (vudc_rx.c) already validate number_of_packets in the CMD_SUBMIT path since commits c6688ef9f297 ("usbip: fix stub_rx: harden CMD_SUBMIT path to handle malicious input") and b78d830f0049 ("usbip: fix vudc_rx: harden CMD_SUBMIT path to handle malicious input"). The server side validates against USBIP_MAX_ISO_PACKETS because no URB exists yet at that point. On the client side we have the original URB, so we can use the tighter bound: the response must not exceed the original number_of_packets. This mirrors the existing validation of actual_length against transfer_buffer_length in usbip_recv_xbuff(), which checks the response value against the original allocation size. Kelvin Mbogo's series ("usb: usbip: fix integer overflow in usbip_recv_iso()", v2) hardens the receive-side functions themselves; this patch complements that work by catching the bad value at its source -- in usbip_pack_ret_submit() before the overwrite -- and using the tighter per-URB allocation bound rather than the global USBIP_MAX_ISO_PACKETS limit. Fix this by checking rpdu->number_of_packets against urb->number_of_packets in usbip_pack_ret_submit() before the overwrite. On violation, clamp to zero so that usbip_recv_iso() and usbip_pad_iso() safely return early.
