CVE-2025-0081
Published: 26 August 2025
Summary
CVE-2025-0081 is a high-severity Use of Uninitialized Variable (CWE-457) vulnerability in Google Android. Its CVSS base score is 7.5 (High).
Operationally, ranked in the top 20.3% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
The vulnerability CVE-2025-0081 stems from use of uninitialized data in the dng_lossless_decoder::HuffDecode function of dng_lossless_jpeg.cpp within the DNG SDK. This flaw resides in Android's external DNG processing component and can produce a crash when decoding certain lossless JPEG streams.
An unauthenticated remote attacker can trigger the condition by supplying a malicious DNG image over the network. Successful exploitation yields a denial-of-service outcome that requires no user interaction and no additional execution privileges, consistent with the CVSS 7.5 rating that emphasizes high availability impact.
The March 2025 Android security bulletin and the referenced commit in the platform/external/dng_sdk repository describe the fix as explicit initialization of decoder state before Huffman decoding proceeds.
EPSS remains flat at 0.0125 with no material rise after disclosure.
