Summary

qt6-qtbase security update

Details

Qt is a software toolkit for developing applications.

Security Fix(es):

A NULL pointer dereference vulnerability in the Qt QCborValue to JSON conversion of the Qt Core module.(CVE-2026-105924)

Out-of-bounds read in the QAuthenticator NTLM authentication handling in the Qt Network module in Qt Group Qt allows remote attackers to obtain sensitive information (heap memory contents) or cause a denial of service (application crash) via a crafted NTLM challenge sent by a malicious server or proxy, when an application using QNetworkAccessManager or QTcpSocket authenticates with NTLM.(CVE-2026-105946)

Specially crafted CBOR input passed to QCborValue::fromCbor() in Qt Core can cause an out-of-bounds read, which may crash the application and could expose information.(CVE-2026-107157)

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)
