media: si470x: Fix use-after-free in si470x_int_in_callback()

2022-12-07T16:58:47+00:00

syzbot reported use-after-free in si470x_int_in_callback() [1]. This indicates that urb->context, which contains struct si470x_device object, is freed when si470x_int_in_callback() is called. The cause of this issue is that si470x_int_in_callback() is called for freed urb. si470x_usb_driver_probe() calls si470x_start_usb(), which then calls usb_submit_urb() and si470x_start(). If si470x_start_usb() fails, si470x_usb_driver_probe() doesn't kill urb, but it just frees struct si470x_device object, as depicted below: si470x_usb_driver_probe() ... si470x_start_usb() ... usb_submit_urb() retval = si470x_start() return retval if (retval < 0) free struct si470x_device object, but don't kill urb This patch fixes this issue by killing urb when si470x_start_usb() fails and urb is submitted. If si470x_start_usb() fails and urb is not submitted, i.e. submitting usb fails, it just frees struct si470x_device object.

Merge tag 'br-v6.2g' of git://linuxtv.org/hverkuil/media_tree into media_stage

2022-11-25T07:55:21+00:00

Despite being big, the changes here are trivial: they just change the probing method for I2C. So, apply it as a merge.

Pull missed media updates from Mauro Carvalho Chehab: "It seems I screwed-up my previous pull request: it ends up that only half of the media patches that were in linux-next got merged in -rc1. The script which creates the signed tags silently failed due to 5.19->6.0 so it ended generating a tag with incomplete stuff. So here are the missing parts: - a DVB core security fix - lots of fixes and cleanups for atomisp staging driver - old drivers that are VB1 are being moved to staging to be deprecated - several driver updates - mostly for embedded systems, but there are also some things addressing issues with some PC webcams, in the UVC video driver" * tag 'media/v6.1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (163 commits) media: sun6i-csi: Move csi buffer definition to main header file media: sun6i-csi: Introduce and use video helper functions media: sun6i-csi: Add media ops with link notify callback media: sun6i-csi: Remove controls handler from the driver media: sun6i-csi: Register the media device after creation media: sun6i-csi: Pass and store csi device directly in video code media: sun6i-csi: Tidy up video code media: sun6i-csi: Tidy up v4l2 code media: sun6i-csi: Tidy up Kconfig media: sun6i-csi: Use runtime pm for clocks and reset media: sun6i-csi: Define and use variant to get module clock rate media: sun6i-csi: Always set exclusive module clock rate media: sun6i-csi: Tidy up platform code media: sun6i-csi: Refactor main driver data structures media: sun6i-csi: Define and use driver name and (reworked) description media: cedrus: Add a Kconfig dependency on RESET_CONTROLLER media: sun8i-rotate: Add a Kconfig dependency on RESET_CONTROLLER media: sun8i-di: Add a Kconfig dependency on RESET_CONTROLLER media: sun4i-csi: Add a Kconfig dependency on RESET_CONTROLLER media: sun6i-csi: Add a Kconfig dependency on RESET_CONTROLLER ...
