CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:HSummary
CVE-2025-22423 is a high-severity Out-of-bounds Read (CWE-125) vulnerability in Google Android. Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 22th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SA-8 (Security and Privacy Engineering Principles) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-22423 is a missing-bounds-check flaw in the ParseTag function of dng_ifd.cpp within the external/dng_sdk component used by Android for processing DNG-format images. The issue is tracked as CWE-125 and carries a CVSS 3.1 base score of 7.5, reflecting network-reachable denial-of-service impact without any confidentiality or integrity loss.
An unauthenticated remote attacker can supply a crafted DNG file that triggers the out-of-bounds read during tag parsing; because the renderer runs with no special privileges required and needs no user interaction, successful exploitation simply crashes the image-processing pipeline and produces a denial of service.
The Android Security Bulletin for April 2025 and the corresponding AOSP commit 748dbd7dfcecb19f3a19caaba4285e059f32d2dd address the vulnerability by adding the missing bounds validation; devices should be updated to a build that incorporates this change. EPSS remains flat at 0.0130 with no observed rise after disclosure.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation directly finds out-of-bounds read flaws through static analysis, fuzzing, and dynamic bounds checks.
Secure engineering principles require bounds checking and memory-safe constructs that stop out-of-bounds reads from being introduced.
Process isolation confines the effects of an out-of-bounds read to the compromised process.
Input validation rejects malformed indices or lengths that would otherwise cause reads outside buffer bounds.

Secure-development practices such as bounds checking and memory-safe languages directly prevent out-of-bounds reads.
Vulnerability scanning and recording can discover instances of out-of-bounds reads after code is deployed.

Security testing in development and acceptance includes fuzzing and static analysis that detect out-of-bounds read defects before release.
Logging can record evidence of an out-of-bounds read but does not prevent the weakness itself.
Secure development life cycle mandates input validation and bounds checking that directly prevent out-of-bounds reads.
Application security requirements include explicit bounds and memory-safety specifications that mitigate buffer over-reads.
Secure system architecture and engineering principles require memory-safe design patterns and runtime protections against out-of-bounds access.
Secure coding standards explicitly forbid unsafe pointer arithmetic and mandate bounds-checked reads, eliminating CWE-125.
