Deeper analysis
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.
