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

CVE-2025-47364 is a memory corruption vulnerability caused by an integer overflow (CWE-190) during the calculation of an offset from the partition start point. It affects components within Qualcomm products, as documented in the vendor's security bulletin.

The vulnerability carries a CVSS v3.1 base score of 6.8 (AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H). Attackers with physical access to an affected device can exploit it with low attack complexity, requiring no privileges or user interaction, potentially resulting in high impacts to confidentiality, integrity, and availability via memory corruption.

Mitigation details are provided in the Qualcomm February 2026 security bulletin, available at https://docs.qualcomm.com/product/publicresources/securitybulletin/february-2026-bulletin.html.

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.
