CVE-2016-3861

Status: ModifiedHigh (7.8)—Exploit

Severity7.8High · CVSS 3.0

Exploitation probability8.29 %higher than 95% of CVEs

Active exploitationNonot in the CISA catalog

Public exploitAvailablePublished on Exploit-DB · Proof of concept on GitHub (unverified)

LibUtils in Android 4.x before 4.4.4, 5.0.x before 5.0.2, 5.1.x before 5.1.1, 6.x before 2016-09-01, and 7.0 before 2016-09-01 mishandles conversions between Unicode character encodings with different encoding widths, which allows remote attackers to execute arbitrary code or cause a denial of service (heap-based buffer overflow) via a crafted file, aka internal bug 29250543.

CVSS

Base score: 7.8
Version: 3.0
Vector: CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 8.29 %
Percentile among all scored CVEs: 95
Score date: 10/20/2026

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.
