Summary
The Qt Framework, a widely used software development toolkit, is affected by this vulnerability in its CBOR parsing function (QCborValue::fromCbor()). An attacker could exploit it by supplying specially crafted CBOR data, causing the software to read memory beyond its intended boundaries, which could lead to crashes or exposure of sensitive information.
Summarized by anthropic/claude-haiku-5.5. Verify details against the original sources.
