CVE-2021-47612

The Linux Kernel, the operating system core itself.

Security Fix(es):

In the Linux kernel, the following vulnerability has been resolved:

nfc: fix segfault in nfc_genl_dump_devices_done

When kmalloc in nfc_genl_dump_devices() fails then nfc_genl_dump_devices_done() segfaults as below

In the Linux kernel, the following vulnerability has been resolved:

Drivers: hv: vmbus: Fix memory leak in vmbus_add_channel_kobj

kobject_init_and_add() takes reference even when it fails. According to the doc of kobject_init_and_add()?

If this function returns an error, kobject_put() must be called to properly clean up the memory associated with the object.

Fix memory leak by calling kobject_put().(CVE-2022-48775)

In the Linux kernel, the following vulnerability has been resolved:

nvme-rdma: fix possible use-after-free in transport error_recovery work

While nvme_rdma_submit_async_event_work is checking the ctrl and queue state before preparing the AER command and scheduling io_work, in order to fully prevent a race where this check is not reliable the error recovery work must flush async_event_work before continuing to destroy the admin queue after setting the ctrl state to RESETTING such that there is no race .submit_async_event and the error recovery handler itself changing the ctrl state.(CVE-2022-48788)

In the Linux kernel, the following vulnerability has been resolved:

usb: gadget: Fix use-after-free bug by not setting udc->dev.driver

The syzbot fuzzer found a use-after-free bug:

BUG: KASAN: use-after-free in dev_uevent+0x712/0x780 drivers/base/core.c:2320 Read of size 8 at addr ffff88802b934098 by task udevd/3689

Although the bug manifested in the driver core, the real cause was a race with the gadget core. dev_uevent() does:

if (dev->driver)
	add_uevent_var(env, "DRIVER=%s", dev->driver->name);

and between the test and the dereference of dev->driver, the gadget core sets dev->driver to NULL.

The race wouldn't occur if the gadget core registered its devices on a real bus, using the standard synchronization techniques of the driver core. However, it's not necessary to make such a large change in order to fix this bug; all we need to do is make sure that udc->dev.driver is always NULL.

In fact, there is no reason for udc->dev.driver ever to be set to anything, let alone to the value it currently gets: the address of the gadget's driver. After all, a gadget driver only knows how to manage a gadget, not how to manage a UDC.

This patch simply removes the statements in the gadget core that touch udc->dev.driver.(CVE-2022-48838)
