Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2025-47392 is a memory corruption vulnerability, classified under CWE-190 (Integer Overflow or Wraparound), that occurs when decoding corrupted satellite data files containing invalid signature offsets. It affects components in Qualcomm products, as detailed in the vendor's security bulletin. The vulnerability received a CVSS v3.1 base score of 8.8 (AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), indicating high severity due to its potential for significant impact on confidentiality, integrity, and availability.

An adjacent attacker with low complexity and no privileges or user interaction required can exploit this vulnerability over the adjacent network (AV:A). Successful exploitation enables high-impact outcomes, including unauthorized access to sensitive data (C:H), modification of system integrity (I:H), and disruption of availability (A:H), potentially leading to remote code execution or system compromise through the memory corruption triggered by malformed satellite data processing.

Qualcomm's April 2026 security bulletin at https://docs.qualcomm.com/product/publicresources/securitybulletin/april-2026-bulletin.html provides details on affected products and recommended mitigations or patches. Security practitioners should consult this advisory for specific remediation steps.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation (static analysis, fuzzing, unit tests) directly finds integer overflow defects before deployment.

Secure engineering principles require use of safe arithmetic constructs or language features that structurally eliminate integer overflow during calculation.

Input validation enforces bounds on values before arithmetic, stopping the conditions that trigger overflow or wraparound.

finds

Security testing in development can detect integer overflows before release.

prevents

Secure SDLC mandates input validation and arithmetic checks that prevent integer overflows.

degrades

Application security requirements include bounds checking and safe arithmetic to avoid overflow conditions.

degrades

Secure architecture principles require defensive coding patterns that mitigate integer wraparound risks.

prevents

Secure coding standards explicitly forbid unsafe integer operations and mandate overflow-safe constructs.
