| In the Linux kernel, the following vulnerability has been resolved:
habanalabs: fix UAF in export_dmabuf()
As soon as we'd inserted a file reference into descriptor table, another
thread could close it. That's fine for the case when all we are doing is
returning that descriptor to userland (it's a race, but it's a userland
race and there's nothing the kernel can do about it). However, if we
follow fd_install() with any kind of access to objects that would be
destroyed on close (be it the struct file itself or anything destroyed
by its ->release()), we have a UAF.
dma_buf_fd() is a combination of reserving a descriptor and fd_install().
habanalabs export_dmabuf() calls it and then proceeds to access the
objects destroyed on close. In particular, it grabs an extra reference to
another struct file that will be dropped as part of ->release() for ours;
that "will be" is actually "might have already been".
Fix that by reserving descriptor before anything else and do fd_install()
only when everything had been set up. As a side benefit, we no longer
have the failure exit with file already created, but reference to
underlying file (as well as ->dmabuf_export_cnt, etc.) not grabbed yet;
unlike dma_buf_fd(), fd_install() can't fail. |
| In the Linux kernel, the following vulnerability has been resolved:
media: ivsc: Fix crash at shutdown due to missing mei_cldev_disable() calls
Both the ACE and CSI driver are missing a mei_cldev_disable() call in
their remove() function.
This causes the mei_cl client to stay part of the mei_device->file_list
list even though its memory is freed by mei_cl_bus_dev_release() calling
kfree(cldev->cl).
This leads to a use-after-free when mei_vsc_remove() runs mei_stop()
which first removes all mei bus devices calling mei_ace_remove() and
mei_csi_remove() followed by mei_cl_bus_dev_release() and then calls
mei_cl_all_disconnect() which walks over mei_device->file_list dereferecing
the just freed cldev->cl.
And mei_vsc_remove() it self is run at shutdown because of the
platform_device_unregister(tp->pdev) in vsc_tp_shutdown()
When building a kernel with KASAN this leads to the following KASAN report:

Add the missing mei_cldev_disable() calls so that the mei_cl gets removed
from mei_device->file_list before it is freed to fix this. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/xe/migrate: prevent potential UAF
If we hit the error path, the previous fence (if there is one) has
already been put() prior to this, so doing a fence_wait could lead to
UAF. Tweak the flow to do to the put() until after we do the wait.
(cherry picked from commit 9b7ca35ed28fe5fad86e9d9c24ebd1271e4c9c3e) |
| In the Linux kernel, the following vulnerability has been resolved:
drm/hisilicon/hibmc: fix irq_request()'s irq name variable is local
The local variable is passed in request_irq (), and there will be use
after free problem, which will make request_irq failed. Using the global
irq name instead of it to fix. |
