CVE-2022-40983

Status: ModifiedHigh (8.8)—

An integer overflow vulnerability exists in the QML QtScript Reflect API of Qt Project Qt 6.3.2. A specially-crafted javascript code can trigger an integer overflow during memory allocation, which can lead to arbitrary code execution. Target application would need to access a malicious web page to trigger this vulnerability.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
