CVE-2025-37851
📋 TL;DR
A buffer overflow vulnerability exists in the Linux kernel's OMAPFB display driver when processing certain 'plane' parameter values. This could allow local attackers to crash the system or potentially execute arbitrary code. Affects Linux systems using OMAP display hardware.
💻 Affected Systems
- Linux kernel

Learn more about Linux Kernel →⚠️ Risk & Real-World Impact
Worst Case
Local privilege escalation leading to kernel compromise and full system control
Likely Case
Kernel panic or system crash causing denial of service
If Mitigated
System remains stable with no impact if parameter validation prevents invalid values
🎯 Exploit Status
Requires local access and ability to trigger specific display driver functions
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Kernel commits: 09dbf22fd68c2f1a81ab89670ffa1ec3033436c4, 3e411827f31db7f938a30a3c7a7599839401ec30, 4efd8ef5e40f2c7a4a91a5a9f03140bfa827da89, 52eafaa56f8f6d6a0cdff9282b25b4acbde34edc, 660a53a0694d1f3789802509fe729dd4656fc5e0
Vendor Advisory: https://git.kernel.org/stable/c/09dbf22fd68c2f1a81ab89670ffa1ec3033436c4
Restart Required: Yes
Instructions:
1. Update Linux kernel to version containing the fix commits. 2. Rebuild kernel if compiling from source. 3. Reboot system to load patched kernel.
🔧 Temporary Workarounds
Disable OMAPFB driver
linuxRemove or disable the vulnerable OMAPFB display driver module
modprobe -r omapfb
echo 'blacklist omapfb' >> /etc/modprobe.d/blacklist.conf
🧯 If You Can't Patch
- Restrict local user access to systems with OMAP hardware
- Implement strict access controls and monitoring for systems using OMAP display drivers
🔍 How to Verify
Check if Vulnerable:
Check kernel version and verify OMAPFB driver is loaded: lsmod | grep omapfbCheck Version:
uname -rVerify Fix Applied:
Verify kernel version includes fix commits and OMAPFB driver loads without errors📡 Detection & Monitoring
Log Indicators:
- Kernel panic messages
- OMAPFB driver crash logs
- System crash/reboot events
Network Indicators:
- None - local vulnerability only
