Summary: qt6-qtbase security update

Details: Qt is a software toolkit for developing applications. Security Fix(es): QDomDocument XML parsing is vulnerable to a remotely-triggerable denial-of-service crash when processing untrusted input.(CVE-2026-19248) Out-of-bounds read (buffer over-read) in the HTTP Cache-Control response header parsing in the QtNetwork module in Qt Group Qt 6.0.0 through 6.8.8, and 6.9.0 through 6.11.1, allows remote attackers to cause a denial of service (application crash) via an excessively large Cache-Control header value returned by an untrusted or compromised HTTP server to an application using QNetworkAccessManager. Only the client side of the connection is affected and 32-bit builds are not affected; the out-of-bounds access is read-only, with no information disclosure and no code execution.(CVE-2026-76151)
