Please review this set of changes for scarthgap and have comments back by
end of day Tuesday, March 31.
Passed a-full on autobuilder:
https://autobuilder.yoctoproject.org/valkyrie/#/builders/29/builds/3546
Note: This particular build had a gnutls patch that I removed because it needed a small change[0].
Build (currently running) without the gnutls patch: https://autobuilder.yoctoproject.org/valkyrie/#/builders/29/builds/3551

CVE-2026-26007 is fixed upstream in version 46.0.5.
Our current version (42.0.5, scarthgap) is still reported as vulnerable
by NVD.
Backport the upstream fix to address this CVE.

+Subject: [PATCH] EC check key on cofactor > 1
+
+An attacker could create a malicious public key that reveals portions of
+your private key when using certain uncommon elliptic curves (binary
+curves). This version now includes additional security checks to
+prevent this attack. This issue only affects binary elliptic curves,
+which are rarely used in real-world applications. Credit to **XlabAI
+Team of Tencent Xuanwu Lab and Atuin Automated Vulnerability Discovery
+Engine** for reporting the issue. **CVE-2026-26007**
+
+This is a partial backport of upstream commit
+0eebb9dbb6343d9bc1d91e5a2482ed4e054a6d8c, to only include what's
+relevant for CVE-2026-26007.

When SPDX_INCLUDE_COMPILED_SOURCES is enabled, only include the
source code files that are used during compilation.
It uses debugsource information generated during do_package.
This enables an external tool to use the SPDX information to disregard
vulnerabilities that are not compiled.
As example, when used with the default config with linux-yocto, the spdx size is
reduced from 156MB to 61MB.
(From OE-Core rev: c6a2f1fca76fae4c3ea471a0c63d0b453beea968)
Adapted to existing files for SPDX3.0
Tested with:
- bitbake world on oe-core
- oe-selftest --run-tests spdx.SPDX30Check
Regarding SPDX2.2, the respective backport was already performed in
OE-Core rev: a2866934e58fb377a73e87576c8594988a63ad1b

glibc-2.43 isn't used in OE builds yet, but this fixes dtc-native:

+Subject: [PATCH] Fix discarded const qualifiers
+
+It's unsafe to implicitly discard the const qualifier on a pointer. In
+overlay_fixup_phandle(), this was probably just an oversight, and making
+the "sep" variable a const char * is sufficient to fix it.
+
+In create_node(), however, the "p" variable is directly modifying the
+buffer pointed to by "const char* node_name". To fix this, we need to
+actually make a duplicate of the buffer and operate on that instead.
+
+This introduces a malloc()/free() and an unbounded strdup() into the
+operation, but fdtput isn't a long-running service and the node_name
+argument comes directly from argv, so this shouldn't introduce a
+significant performance impact.

+
+When the servername callback raises an exception, call sys.excepthook
+with the exception info and return SSL_TLSEXT_ERR_ALERT_FATAL to abort
+the handshake. Previously, exceptions would propagate uncaught through

Tho, (I hope this is the proper way to address you, if not, sorry!)
This "Upstream-Status:" after the "---" triggers a patchtest failure:
FAIL: test Upstream-Status presence: Upstream-Status is present only
after the patch scissors. It must be placed in the patch header before
the scissors line.
(test_patch.TestPatch.test_upstream_status_presence_format)
This is very minor for stables where a patch rebase following an upgrade
is a very rare event.
But, that said, if you can send a v2 patch with the "Upstream-Status"
above the "---", I'll take it.
As a side note: this particular patchtest test is not in scarthgap
patchtech, I'll try to backport it.
Thanks!

Hello Martin,
FYI, while it looked good, this patch and your whole series about glibc
2.43 support:
* [scarthgap 04/11] dtc: backport fix for build with glibc-2.43
* [scarthgap 05/11] pseudo: Add fix for glibc 2.43
* [scarthgap 06/11] yocto-uninative: Update to 5.0 for needed patchelf updates
* [scarthgap 07/11] yocto-uninative: Update to 5.1 for glibc 2.43
* [scarthgap 08/11] elfutils: don't add -Werror to avoid discarded-qualifiers
* [scarthgap 09/11] binutils: backport patch to fix build with glibc-2.43 on host
... will be put on hold until I can test it: So, not until Ubuntu 26.04
is released and the autobuilder gain an Ubuntu 26.04 worker (most likely
after Wrynose release).
Thanks!

OK, I have similar 7 patch series with additional fix for m4, gettext,
systemd for whinlatter. Should I send it for review or put it on hold
as well?
I've built images with latest 26.04 snapshot in docker with scarthgap,
whinlatter, wrynose for rpi - there might be more native recipes used
for other BSPs (or included only in bitbake world), but build-wise
these 2 series should cover most of it.

Hold them as well. For the same reason, I won't be able to accept them
before whinlatter EOL.

Hello Yoann,
some of the follow-up glibc/gcc patches for ubuntu-26.04 are now in
your contrib/stable/scarthgap-nut, but the 6 changes from this PR are
still removed, is it intentional now when similar changes are going to
be merged in whinlatter? Should I resend the 6 on top of current
stable/scarthgap-nut?
Regards,

Was the commit below not picked, or am I missing something?
commit b24d5cda19136fb8120154279eedd55d162b4640
Author: João Marcos Costa (Schneider Electric)
<joaomarcos.costa@bootlin.com>
Date: Fri Apr 3 11:32:30 2026 +0200
linux-yocto/6.6: update CVE exclusions (6.6.123)
This new version of cve-exclusion_6.6.inc was generated with oe-core's
latest version of the generate-cve-exclusions.py.
Regarding the database used and how this file was generated:
Generated at 2026-04-03 09:30:32.247568+00:00 for kernel version
6.6.123
From cvelistV5 cve_2026-04-03_0700Z
The backporting of the generate-cve-exclusions.py script from master to
Scarthgap is handled in a different patch.
Signed-off-by: João Marcos Costa (Schneider Electric)
<joaomarcos.costa@bootlin.com>
However, I see the commit below, prior to this one, was kept:
linux/generate-cve-exclusions: backport script from master branch
I'm not really used to the backports schedule/workflow, so please excuse
me if I misinterpreted something.
Thanks!

This patch triggered a problem in our infra. I received it directly from
you but it is missing from lore. And lore feeds patchwork, and I use
patchwork to prepare my review branch...
This is a known problem: 16167 – Missing (big) patch in patchwork
https://bugzilla.yoctoproject.org/show_bug.cgi?id=16167
I've reopened and added your patch to the bug log.
I will now integrate your patch in my review branch.
Thanks for the report, otherwise I would have missed it.
I'll try to check for this issue in the future but this will be hard to
spot. If you send a similar patch in the future don't hesitate to ping
me if you see it missing during the patch review period.
Regards,

I've put some patches that I could not apply directly aside to test the
others.

Yes, please. :)
That will be easier for me.
