CVE-2025-47392 Overview
CVE-2025-47392 is a memory corruption vulnerability affecting numerous Qualcomm chipsets and firmware components. The vulnerability occurs when processing corrupted satellite data files that contain invalid signature offsets, potentially allowing an attacker within adjacent network range to achieve code execution or cause system instability. This Integer Overflow vulnerability (CWE-190) affects a wide range of Qualcomm products including Snapdragon mobile platforms, 5G modems, wireless connectivity chips, and audio codecs used in smartphones, tablets, wearables, automotive systems, and IoT devices.

Technical Details for CVE-2025-47392
Vulnerability Analysis
This vulnerability stems from an integer overflow condition (CWE-190) in the satellite data file decoding routines within affected Qualcomm firmware. When processing satellite navigation or positioning data files, the firmware parses signature offset values embedded within the file headers. The vulnerability manifests when a maliciously crafted file contains invalid or excessively large signature offset values that trigger an integer overflow during offset calculation.
The adjacent network attack vector indicates that exploitation requires the attacker to be on the same network segment as the target device, though no authentication or user interaction is required. This could occur through scenarios such as a compromised wireless access point, rogue base station, or malicious device on the same local network that can inject or serve malformed satellite data files.
Successful exploitation can lead to memory corruption, potentially allowing an attacker to achieve arbitrary code execution with the privileges of the affected firmware component, read or modify sensitive data, or cause a denial of service condition on the affected device.
Root Cause
The root cause is an integer overflow vulnerability (CWE-190) in the signature offset validation logic. When the firmware calculates memory addresses or buffer sizes using the signature offset values from untrusted input, insufficient bounds checking allows integer overflow conditions to occur. This results in incorrectly calculated memory addresses or undersized buffer allocations, leading to subsequent out-of-bounds memory access operations.
Attack Vector
The attack requires adjacent network access, meaning the attacker must be positioned within the same network segment as the target device. The attack can be executed remotely within this proximity without requiring any authentication credentials or user interaction. Attack scenarios include:
- A malicious actor operating a rogue cellular base station or Wi-Fi access point that serves crafted satellite assistance data
- An attacker on the same local network injecting malicious data into satellite data update streams
- Compromised network infrastructure delivering malformed positioning data files to connected devices
The vulnerability does not require any special privileges or user interaction, making it particularly dangerous in scenarios where devices automatically process satellite data from network sources.
Detection Methods for CVE-2025-47392
Indicators of Compromise
- Unexpected device crashes or reboots during GPS/GNSS operations or when connecting to cellular networks
- Anomalous memory access patterns or segmentation faults in modem or baseband processor logs
- Unusual network traffic patterns involving satellite assistance data protocols (SUPL, A-GPS)
- Device instability correlated with location services or cellular network attachment
Detection Strategies
- Monitor for abnormal firmware behavior or unexpected resets in Qualcomm modem subsystems
- Implement network-level inspection for malformed satellite assistance data payloads
- Deploy endpoint detection solutions capable of monitoring baseband processor health
- Review device logs for repeated crashes in location services or modem-related processes
Monitoring Recommendations
- Enable verbose logging for GNSS and modem subsystems where available
- Monitor for patterns of device instability across fleets of affected Qualcomm-based devices
- Implement network segmentation to limit exposure of vulnerable devices to untrusted adjacent networks
- Deploy SentinelOne agents on supported platforms to detect anomalous behavior patterns associated with memory corruption exploitation
How to Mitigate CVE-2025-47392
Immediate Actions Required
- Review your device inventory to identify systems using affected Qualcomm chipsets and firmware
- Apply firmware updates from device OEMs as they become available incorporating Qualcomm's patches
- Limit device exposure to untrusted networks where possible
- Monitor Qualcomm's security bulletins and OEM security updates for patch availability
Patch Information
Qualcomm has addressed this vulnerability in their April 2026 Security Bulletin. Organizations should consult the Qualcomm April 2026 Security Bulletin for detailed patch information. End users should apply firmware updates through their device manufacturer (OEM) channels, as Qualcomm provides patches to OEMs who then distribute updates to end users.
The patch rollout timeline depends on individual device manufacturers. Contact your device vendor for specific update availability and installation instructions for affected products.
Workarounds
- Restrict device connectivity to trusted networks only until patches can be applied
- Disable automatic satellite assistance data downloads where configurable
- Implement network access controls to limit adjacent network attack surface
- Consider network segmentation to isolate vulnerable devices from potentially compromised network segments
# Example: Verify firmware version on Android devices (requires ADB)
adb shell getprop ro.build.fingerprint
adb shell getprop gsm.version.baseband
# Check for available system updates
adb shell pm list packages | grep -i update
