CVSS 7.8 · HIGH

CVE-2025-47405

Memory corruption when processing camera sensor input/output control codes with invalid output buffers.

Analysis

This is a low-level firmware vulnerability in specific Qualcomm FastConnect chipsets used in high-end mobile devices. While it involves high-severity memory corruption, it is a hardware-specific issue that requires vendor-level security patches and does not directly affect the software development stack, web servers, or DevOps tooling used by the community.

How to read this card

Actively exploited

KEV (Known Exploited Vulnerabilities) is CISA's catalog of CVEs confirmed as actively exploited in the real world. If a CVE is on KEV, someone is already using it in attacks.

CVSS 10.0

CVSS 10.0 — máxima severidad teórica. Explotable de forma remota, sin privilegios, con impacto total. Aún no confirmada como explotada en el mundo real, pero parchea ya.
