CVE-2025-21084
Published: 04 March 2025
Description
Adversaries may exploit software vulnerabilities in an attempt to elevate privileges.
Security Summary
CVE-2025-21084 is a NULL pointer dereference vulnerability (CWE-476) affecting OpenHarmony versions v5.0.2 and prior. Published on 2025-03-04, it enables a local attacker to achieve arbitrary code execution within pre-installed applications.
The vulnerability can be exploited by a local attacker with low privileges (PR:L), requiring low attack complexity (AC:L) and no user interaction (UI:N). Successful exploitation is confined to restricted scenarios and results in low confidentiality impact (C:L) with no integrity or availability effects (I:N/A:N), though the scope is changed (S:C), yielding a CVSS v3.1 base score of 3.8.
