DescriptionNVD

Incorrect boundary conditions in the WebRTC component. This vulnerability was fixed in Firefox 150.

AnalysisAI

Incorrect boundary conditions in Firefox's WebRTC component allow remote attackers to read limited memory contents without authentication. Firefox versions prior to 150 are affected by this low-confidentiality vulnerability, which CVSS rates at 5.3 due to network exploitability without user interaction, though CISA's SSVC framework indicates no current exploitation activity and limited technical impact.
