Analysis Summary
# Vulnerability: Actively Exploited Qualcomm Display Component Zero-Day in Android
## CVE Details
- CVE ID: CVE-2026-21385
- CVSS Score: Information not explicitly provided, but described as **high-severity**.
- CWE: Integer Overflow/Wraparound
## Affected Systems
- Products: Android OS components, specifically Qualcomm chipsets utilizing the Graphics subcomponent.
- Versions: Not explicitly listed, but affected are 235 Qualcomm chipsets. The vulnerability is addressed in the March 2026 Android Security Bulletins (2026-03-01 and 2026-03-05).
- Configurations: Requires local attacker access to the affected display component.
## Vulnerability Description
The vulnerability (CVE-2026-21385) is an **integer overflow or wraparound** located within the **Graphics subcomponent** of Qualcomm firmware. Successful exploitation by a local attacker could lead to **memory corruption**.
## Exploitation
- Status: **Actively exploited in the wild** (limited, targeted exploitation reported by Google).
- Complexity: Implied **Low/Medium** as it requires a local attacker but the severity suggests a high impact once triggered.
- Attack Vector: **Local**
## Impact
- Confidentiality: Undetermined, but memory corruption stemming from a local exploit often implies potential CEs.
- Integrity: **High** (due to memory corruption).
- Availability: **High** (memory corruption/DoS potential).
## Remediation
### Patches
