In the Linux kernel, the following vulnerability has been resolved:
RDMA/srpt: Support specifying the srpt_service_guid parameter
Make loading ib_srpt with this parameter set work. The current behavior is
that setting that parameter while loading the ib_srpt kernel module
triggers the following kernel crash:

In the Linux kernel, the following vulnerability has been resolved:
usb: roles: fix NULL pointer issue when put module's reference
In current design, usb role class driver will get usb_role_switch parent's
module reference after the user get usb_role_switch device and put the
reference after the user put the usb_role_switch device. However, the
parent device of usb_role_switch may be removed before the user put the
usb_role_switch. If so, then, NULL pointer issue will be met when the user
put the parent module's reference.
This will save the module pointer in structure of usb_role_switch. Then,
we don't need to find module by iterating long relations.

In the Linux kernel, the following vulnerability has been resolved:
usb: cdns3: fix memory double free when handle zero packet
829 if (request->complete) {
830 spin_unlock(&priv_dev->lock);
831 usb_gadget_giveback_request(&priv_ep->endpoint,
832 request);
833 spin_lock(&priv_dev->lock);
834 }
835
836 if (request->buf == priv_dev->zlp_buf)
837 cdns3_gadget_ep_free_request(&priv_ep->endpoint, request);
Driver append an additional zero packet request when queue a packet, which
length mod max packet size is 0. When transfer complete, run to line 831,
usb_gadget_giveback_request() will free this requestion. 836 condition is
true, so cdns3_gadget_ep_free_request() free this request again.

usb_gadget_giveback_request() because it is allocated in this driver.

...
cdns3_gadget_ep_free_request(&priv_ep->endpoint, &priv_req->request);

'priv_req' actually free at cdns3_gadget_ep_free_request(). But
list_del_init() use priv_req->list after it.

In the Linux kernel, the following vulnerability has been resolved:
ARM: ep93xx: Add terminator to gpiod_lookup_table
Without the terminator, if a con_id is passed to gpio_find() that
does not exist in the lookup table the function will not stop looping
correctly, and eventually cause an oops.

In the Linux kernel, the following vulnerability has been resolved:
l2tp: pass correct message length to ip6_append_data
l2tp_ip6_sendmsg needs to avoid accounting for the transport header
twice when splicing more data into an already partially-occupied skbuff.
To manage this, we check whether the skbuff contains data using
skb_queue_empty when deciding how much data to append using
ip6_append_data.
However, the code which performed the calculation was incorrect:
ulen = len + skb_queue_empty(&sk->sk_write_queue) ? transhdrlen : 0;
...due to C operator precedence, this ends up setting ulen to
transhdrlen for messages with a non-zero length, which results in
corrupted packets on the wire.
Add parentheses to correct the calculation in line with the original
intent.

sizeof(struct virtio_crypto_akcipher_session_para) is less than
sizeof(struct virtio_crypto_op_ctrl_req::u), copying more bytes from

A vulnerability in the web-based management interface of Cisco Identity Services Engine (ISE) could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack and perform arbitrary actions on an affected device.
This vulnerability is due to insufficient CSRF protections for the web-based management interface of an affected device. An attacker could exploit this vulnerability by persuading a user of the interface to follow a crafted link. A successful exploit could allow the attacker to perform arbitrary actions on the affected device with the privileges of the targeted user.
