Hi Bernd,

Thanks for the patch.

It there is one extra commit pushed upstream addressing another
CVE-2026-4438. See:
https://sourceware.org/git/?p=glibc.git;a=commit;h=dd9945c0ba40d2dbc9eb7c99291ba6b69bd66718

So we should probably bump directly to:
glibc-2.43-17-gdd9945c0ba40d2dbc9eb7c99291ba6b69bd66718

Can you send an updated patch to this newer version, please?
