Description Carlos López 2022-10-04 08:21:01 UTC 
CVE-2022-41849

drivers/video/fbdev/smscufx.c in the Linux kernel through 5.19.12 has a race
condition and resultant use-after-free if a physically proximate attacker
removes a USB device while calling open(), aka a race condition between
ufx_ops_open and ufx_usb_disconnect.

This has not been merged upstream yet.

CONFIG_FB_SMSCUFX is only enabled in the SLE15-SP{3,4} branches for the default armv7hl configuration.
Comment 3 Takashi Iwai 2022-10-04 10:45:03 UTC 
It's in fbdev subsystem tree, commit 6a7bca685c93fd18133d313716e141faac3bddc3.
Will backport it to relevant branches.
Comment 4 Takashi Iwai 2022-10-04 10:52:30 UTC 
The fix backported to SLE15-SP4 and cve/linux-5.3 branches.

Reassigned back to security team.

Comment 29 Jean Delvare 2022-12-08 16:37:30 UTC 
I'm reopening this bug after finding something fishy in our kernel repository.

There are actually 2 recent security fixes to the smscufx driver. The first fix is:

commit 5610bcfe8693c02e2e4c8b31427f1bdbdecc839c
Author: Hyunwoo Kim
Date:   Sun Sep 25 06:32:43 2022 -0700

    fbdev: smscufx: Fix use-after-free in ufx_ops_open()

It was merged upstream in kernel v6.1-rc1, and is associated with CVE-2022-41849.

The second fix is:

commit cc67482c9e5f2c80d62f623bcc347c29f9f648e1
Author: Hyunwoo Kim
Date:   Thu Oct 20 18:15:44 2022 -0700

    fbdev: smscufx: Fix several use-after-free bugs

It was merged upstream in kernel v6.1-rc3. I could not find a CVE number associated with this fix, however, considering that it has the same author and addresses UAFs in the same driver just one month after the first one, I would be tempted to consider that the CVE number actually covers both fixes. While this isn't strictly true, customers may also understand it that way and expect both commits to be backported before we claim that CVE-2022-41849 is fixed.

The current fix situation in our trees is as follows:

* The first bug is fixed in all relevant branches (SLE15-SP2-LTSS, SLE15-SP3, SLE15-SP4, SLE15-SP5). However, the Git-commit and Patch-mainline tags are incorrect in all branches except SLE15-SP3. The SLE15-SP2-LTSS branch still refers to the subsystem maintainer repository commit ID (which is different), while the SLE15-SP4 and SLE15-SP5 branches use the commit ID of the second fix listed above, together with its Patch-mainline information (so v6.1-rc3 instead of v6.1-rc1).

* The second fix is only present in the SLE15-SP3 branch (patches.suse/fbdev-smscufx-Fix-several-use-after-free-bugs.patch, tags are correct).

So we need to fix the incorrect tags of the first patch, and add the second patch, in SLE15-SP2-LTSS, SLE15-SP4 and SLE15-SP5. I'll take care of that if there are no objections.

I'm unsure if this justifies resubmitting these kernels for the upcoming maintenance update, I'll let the Security Team decide.
Comment 30 Takashi Iwai 2022-12-08 17:09:07 UTC 
Note that the person has been reporting many UAF issues in various areas, often several times for the same device driver.  So, the fact that multiple fixes are seen by the same author for the same driver doesn't mean that the CVE mentions for both.

The bug is only for armv7hl and only with the specific hardware, so maybe not worth for MU resubmission.
Comment 31 Jean Delvare 2022-12-08 19:50:07 UTC 
Correcting myself: SLE15-SP2-LTSS is not actually relevant here, as we don't build the smscufx driver in any config. I'll still update the first patch for consistency (if it is there, it should have the right commit ID) but there's no point in spending time backporting the second patch, especially when it doesn't apply cleanly.
Comment 32 Jean Delvare 2022-12-10 12:30:44 UTC 
The problem described in comment #29 is now fixed in SLE15-SP2-LTSS, SLE15-SP4 and SLE15-SP5, therefore we can close this bug again.
