## CVE Details
* **CVE ID:** CVE-2025-26443 (Most serious flaw)
* **CVSS Score:** Not explicitly provided, but designated as "high-severity."
* **CWE:** Not specified, but related to privilege escalation.
## Affected Systems
* **Products:** Android system components (Android Runtime, Android framework, Android system). Also includes components from Arm, Imagination Technologies, and Qualcomm.
* **Versions:** Devices receiving the June 2025 security update (Specific version numbers not listed in the context, but addressed by patch levels 2025-06-01 and 2025-06-05).
* **Configurations:** The most serious flaw (CVE-2025-26443) requires user interaction to trigger.
## Vulnerability Description
Google's June 2025 security update addresses 34 high-severity vulnerabilities across the Android ecosystem. The most critical flaw, **CVE-2025-26443**, resides in the core Android system. Exploitation of this flaw allows an attacker to achieve **local escalation of privilege** without needing any additional pre-existing privileges, provided the attacker can induce user interaction. Other flaws addressed could lead to escalation of privileges, remote code execution, denial of service, and information disclosure.
The update includes fixes for:
* 1 high-severity vulnerability in Android Runtime.
* 11 high-severity vulnerabilities in the Android framework.
* 4 high-severity vulnerabilities in the Android system (including CVE-2025-26443).
* Additional fixes covering Arm, Imagination Technologies, and Qualcomm components across the two patch levels.
## Exploitation
* **Status:** No actively exploited vulnerabilities were disclosed in Google's update. However, three *separate* Qualcomm component zero-day vulnerabilities (CVE-2025-21479, CVE-2025-21480, CVE-2025-27038) fixed in the update are reported by Google's TAG to be "under limited, targeted exploitation," and CISA has added them to the KEV catalog.
* **Complexity:** For CVE-2025-26443, exploitation requires user interaction, suggesting **Medium** complexity for successful exploitation via that specific vector.
* **Attack Vector:** Local (for CVE-2025-26443). Other vulnerabilities may utilize Network or Local vectors.
## Impact
* **Confidentiality:** Potential for information disclosure.
* **Integrity:** Potential for escalation of privileges.
* **Availability:** Potential for denial of service.
## Remediation
### Patches
* The Android security update released includes fixes corresponding to patch levels **2025-06-01** and **2025-06-05**.
* Source code patches for all 34 vulnerabilities will be released to the Android Open Source Project repository by **Wednesday** (following the article date).
### Workarounds
* No specific workarounds were mentioned for the 34 vulnerabilities addressed, but immediate application of the security update is implied as the primary remedy.
## Detection
* **Indicators of Compromise:** Not detailed in the summary, but monitoring for unauthorized privilege escalation or unexpected system behavior related to the affected components is recommended.
* **Detection Methods and Tools:** Monitoring device logs for unusual activity stemming from the Android Runtime, Framework, or System services. Users should refer to vendor advisories for specific IOCs related to the exploited Qualcomm components.
