CVE-2026-107157 1 Qt 2 Qt, Qtbase 2026-10-27 N/A
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-2026-107472 1 Qt 3 Qt, Qt5compat, Qtbase 2026-10-27 N/A
An out-of-bounds read vulnerability in the QTextCodec TSCII encoding of the Qt 5 Compatibility APIs module (Qt Core in Qt 5 and earlier) impacts Qt. Applications that convert text to the TSCII encoding through QTextCodec may read memory outside the input buffer, which can cause the application to crash or misinterpret the data.
CVE-2026-105946 1 Qt 2 Qt, Qtbase 2026-10-27 N/A
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-2026-96432 1 Qt 2 Qt, Qtbase 2026-10-26 N/A
A malicious or compromised HTTP/2 server withholding SETTINGS ACK can send RST_STREAM on a completed stream, planting a null pointer, and then send a PUSH_PROMISE for that stream, causing a null pointer dereference in the QNetworkAccessManager class of the Qt Network module that crashes the application.
CVE-2026-16762 1 Qt 2 Qt, Qtbase 2026-10-23 N/A
An attacker able to supply a crafted XML document to an application using QXmlStreamReader can cause disproportionate CPU consumption during parsing, making the application unresponsive (denial of service). Exploitation requires only that the application parse attacker-influenced XML; no authentication, privileges, or user interaction beyond ingesting the input are needed. There is no loss of confidentiality or integrity — no data disclosure, data modification, or code execution — and the impact is contained to the affected process.
CVE-2026-105923 1 Qt 2 Qt, Qtbase 2026-10-21 5.5 Medium
A malicious SVG can trigger an integer overflow which in turn triggers a null-pointer dereference in VectorImage QML Type.
CVE-2026-101201 1 Qt 3 Qt, Qt5compat, Qtbase 2026-10-20 5.5 Medium
A malformed header in the binary file fed to QBinaryJson::fromBinaryData() can cause undefined behaviour because of out-of-bounds read.
CVE-2019-18281 3 Debian, Qt, Redhat 3 Debian Linux, Qtbase, Enterprise Linux 2024-11-21 4.3 Medium
An out-of-bounds memory access in the generateDirectionalRuns() function in qtextengine.cpp in Qt qtbase 5.11.x and 5.12.x before 5.12.5 allows attackers to cause a denial of service by crashing an application via a text file containing many directional characters.
