CVE-2025-52519
Published: 05 January 2026
Summary
CVE-2025-52519 is a high-severity Improper Input Validation (CWE-20) vulnerability in Samsung Exynos 1330 Firmware. Its CVSS base score is 7.1 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Data from Local System (T1005); ranked at the 7.5th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and AC-3 (Access Enforcement).
Deeper analysis
CVE-2025-52519 is a vulnerability discovered in the Camera component of Samsung Mobile Processor and Wearable Processor Exynos 1330, 1380, 1480, 2400, 1580, and 2500. It stems from improper validation of user-space input (CWE-20) in the issimian device driver, enabling information disclosure and denial of service. The issue carries a CVSS v3.1 base score of 7.1 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H) and was published on 2026-01-05.
A local attacker with low privileges can exploit this vulnerability with low complexity and no user interaction required. Successful exploitation allows high-impact confidentiality loss through information disclosure and high-impact availability disruption via denial of service, without affecting integrity or changing scope.

Why these techniques?
Local kernel driver input validation flaw directly enables unauthorized data reads from the system (info disclosure) and targeted DoS via exploitation of the driver.

Mitigating Controls (NIST 800-53 r5) AI
Directly requires validation of user-space inputs to the issimian driver, eliminating the root cause (CWE-20) that enables local information disclosure and DoS.
Enforces access-control decisions on the device driver so that low-privileged local processes cannot reach the vulnerable input paths.
Isolates the camera driver process, limiting the blast radius of any successful input-validation bypass to information disclosure or DoS within that process only.
