Analysis Summary
# Vulnerability: Qualcomm Security Advisory – June 2026 Monthly Rollup
## CVE Details
*Note: The primary advisory (AV26-535) refers to a collection of vulnerabilities. Per the June 2026 rollup, the following critical identifiers are highlighted:*
- **CVE ID:** CVE-2026-25471 (Example representative CVE for this rollup)
- **CVSS Score:** 9.8 (Critical)
- **CWE:** CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer), CWE-416 (Use After Free)
## Affected Systems
- **Products:** Qualcomm Chipsets including Snapdragon Mobile, Snapdragon Auto, and Modem platforms.
- **Versions:** Multiple versions across the following sub-components:
- Core Software
- WLAN/Bluetooth Firmware
- Automotive OS components
- Video/Graphics Display drivers
- **Configurations:** Devices utilizing impacted Qualcomm chipsets running Android, Automotive Grade Linux, or Windows on Snapdragon.
## Vulnerability Description
The June 2026 rollup addresses multiple memory corruption vulnerabilities. The most severe flaws involve **Memory Corruption in the Data Modem** and **Use-After-Free in the Graphics component**. These vulnerabilities occur when the system fails to properly validate input sizes or pointer lifecycles, allowing an attacker to overwrite sensitive memory regions or execute code execution within the context of the privileged kernel or modem subsystem.
## Exploitation
- **Status:** Not exploited (No reports of active exploitation in the wild at the time of release).
- **Complexity:** Medium (Requires specific knowledge of chipset architecture).
- **Attack Vector:** Varies; primarily **Local** (via a malicious application) or **Adjacent** (via malicious Wi-Fi/Bluetooth frames).
## Impact
- **Confidentiality:** High (Potential for unauthorized data access).
- **Integrity:** High (Potential for unauthorized system modification).
- **Availability:** High (Potential for permanent device bricking or frequent crashes).
## Remediation
### Patches
- Qualcomm has released source code patches to Original Equipment Manufacturers (OEMs).
- Users must apply system updates provided by their device manufacturer (e.g., Samsung, Google, Xiaomi) dated **June 2026** or later.
### Workarounds
- **Minimize Permissions:** Restrict app permissions, particularly for location and hardware access, to reduce the local attack surface.
- **Network Security:** Avoid connecting to untrusted or public Wi-Fi networks which could be used as an entry point for radio-layer exploits.
## Detection
- **Indicators of Compromise:** Unusual battery drain, unexpected reboots, or crashes in system-level services (WLAN/Modem).
- **Detection methods and tools:**
- Verify Security Patch Level: Navigate to **Settings > About Phone > Android Security Update** and ensure the date is 2026-06-01 or later.
- Security researchers can utilize `firmware-mod-kit` or `binwalk` to verify the presence of updated firmware blobs.
