CVE-2025-5992: CWE-20 Improper Input Validation in Qt
When passing values outside of the expected range to QColorTransferGenericFunction it can cause a denial of service, for example, this can happen when passing a specifically crafted ICC profile to QColorSpace::fromICCProfile. This issue affects Qt from 6.6.0 through 6.8.3, from 6.9.0 through 6.9.1. This is fixed in 6.8.4 and 6.9.2.
AI Analysis
Technical Summary
CVE-2025-5992 is an improper input validation vulnerability (CWE-20) in the Qt framework. When values outside the expected range are passed to the QColorTransferGenericFunction, it can cause a denial of service condition. This can occur, for example, when a specially crafted ICC profile is passed to QColorSpace::fromICCProfile. The issue affects Qt versions 6.6.0 through 6.8.3 and 6.9.0 through 6.9.1. The vulnerability is resolved in Qt versions 6.8.4 and 6.9.2.
Potential Impact
An attacker can cause a denial of service by supplying out-of-range input values to the affected function, potentially crashing or disrupting applications using the vulnerable Qt versions. The impact is limited to denial of service with no indication of code execution or data compromise. The CVSS score of 2.3 reflects the low severity and the requirement for user interaction and high attack complexity.
Mitigation Recommendations
This vulnerability is fixed in Qt versions 6.8.4 and 6.9.2. Users and organizations should upgrade to these or later versions to remediate the issue. No other mitigation or workaround is indicated.
