I currently think the tracking from Neil was correct. The Issue was introduced by the commit 2https://github.com/qt/qtbase/commit/6869d2463a2e0d71bd04dbc82f5d6ef4933dc510 . Now the maintainer has today uploaded https://tracker.debian.org/news/1281817/accepted-qtbase-opensource-src-5152dfsg-14-source-into-unstable/ claiming it fixes CVE-2021-38593. But looking at the changes it looks that the debian/patches/CVE-2021-38593.diff patch both used https://code.qt.io/cgit/qt/qtbase.git/commit/?id=f4d791b330d02777 introducing the needed "breaking" change, and then as well the fix. See as well https://bugzilla.suse.com/show_bug.cgi?id=1189652#c2 arguing in the same direction. We should recheck, but currently tend to that the tracking is already correct. Regards, Salvatore
