CVE-2025-27048

7.8 HIGH

📋 TL;DR

This vulnerability allows attackers to cause memory corruption through improper handling of IOCTL calls in Qualcomm camera platform drivers. Successful exploitation could lead to privilege escalation or denial of service. Affects devices using Qualcomm chipsets with vulnerable camera drivers.

💻 Affected Systems

Products:
  • Qualcomm camera platform drivers
Versions: Specific versions not detailed in reference; consult Qualcomm October 2025 bulletin
Operating Systems: Android, Linux-based systems using Qualcomm chipsets
Default Config Vulnerable: ⚠️ Yes
Notes: Affects devices with Qualcomm camera hardware; exact chipset models not specified in provided reference.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Local attacker gains kernel-level privileges, leading to complete system compromise, data theft, or persistent backdoor installation.

🟠

Likely Case

Local privilege escalation allowing attackers to bypass security controls and execute arbitrary code with elevated permissions.

🟢

If Mitigated

Denial of service through system crash or instability if exploitation fails or is detected.

🌐 Internet-Facing: LOW - Requires local access to device; not directly exploitable over network.
🏢 Internal Only: MEDIUM - Local attackers on shared systems or compromised user accounts could exploit this vulnerability.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: MEDIUM

Requires local access and ability to make IOCTL calls to camera driver; typical exploitation would involve crafting malicious IOCTL requests.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Refer to Qualcomm October 2025 security bulletin for specific patched versions

Vendor Advisory: https://docs.qualcomm.com/product/publicresources/securitybulletin/october-2025-bulletin.html

Restart Required: Yes

Instructions:

1. Check Qualcomm October 2025 security bulletin for affected chipset models. 2. Obtain updated camera driver from device manufacturer or Qualcomm. 3. Apply driver update following manufacturer instructions. 4. Reboot device to load patched driver.

🔧 Temporary Workarounds

Restrict camera driver access

linux

Limit access to camera driver IOCTL interface using SELinux/AppArmor policies or file permissions

chmod 600 /dev/camera_driver_device
setenforce 1 (if using SELinux)

Disable camera functionality

linux

Temporarily disable camera hardware if not required for device operation

echo 0 > /sys/class/camera/enable
rmmod camera_driver_module

🧯 If You Can't Patch

  • Implement strict access controls to prevent unauthorized users from making IOCTL calls
  • Monitor system logs for unusual camera driver activity or crash reports

🔍 How to Verify

Check if Vulnerable:

Check Qualcomm chipset model and driver version against October 2025 security bulletin

Check Version:

cat /sys/module/camera_driver/version or check device manufacturer's security patch level

Verify Fix Applied:

Verify camera driver version has been updated to patched version from bulletin

📡 Detection & Monitoring

Log Indicators:

  • Kernel panic or oops messages related to camera driver
  • Unusual IOCTL calls to camera device with malformed parameters

Network Indicators:

  • Not applicable - local exploitation only

SIEM Query:

source="kernel" AND ("camera" OR "IOCTL") AND ("panic" OR "oops" OR "corruption")
