Hi,

The following vulnerability was published for qtbase-opensource-src-gles.

CVE-2025-5455[0]:
| An issue was found in the private API function qDecodeDataUrl() in
| QtCore, which is used in QTextDocument and QNetworkReply, and,
| potentially, in user code.  If the function was called with
| malformed data, for example, an URL that contained a "charset"
| parameter that lacked a value (such as "data:charset,"), and Qt was
| built with assertions enabled, then it would hit an assertion,
| resulting in a denial of service (abort).  This impacts Qt up to
| 5.15.18, 6.0.0->6.5.8, 6.6.0->6.8.3 and 6.9.0. This has been fixed
| in 5.15.19, 6.5.9, 6.8.4 and 6.9.1.

This does not need fixing in qtbase-opensource-src-gles. The vulnerability
is in QtCore library, but the -gles source package does not build its own
QtCore, it reuses one from qtbase-opensource-src.
