CVE-2026-24830

9.8 CRITICAL

📋 TL;DR

An integer overflow vulnerability in Ralim IronOS firmware allows attackers to cause memory corruption through improper arithmetic operations. This affects all IronOS devices running versions before v2.23-rc2, potentially leading to system crashes or arbitrary code execution.

💻 Affected Systems

Products:
  • Ralim IronOS firmware
Versions: All versions before v2.23-rc2
Operating Systems: Embedded firmware for soldering iron devices
Default Config Vulnerable: ⚠️ Yes
Notes: Affects all devices running vulnerable IronOS firmware regardless of configuration

⚠️ Manual Verification Required

This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.

Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

  2. Check vendor security advisories for your specific version
  3. Test if the vulnerability is exploitable in your environment
  4. Consider updating to the latest version as a precaution

⚠️ Risk & Real-World Impact

🔴

Worst Case

Remote code execution leading to complete device compromise, data theft, or device bricking

🟠

Likely Case

System instability, crashes, or denial of service affecting device functionality

🟢

If Mitigated

Limited impact with proper network segmentation and access controls

🌐 Internet-Facing: HIGH - Firmware vulnerabilities in IoT devices often expose them to remote exploitation
🏢 Internal Only: MEDIUM - Internal attackers could still exploit if they have network access

🎯 Exploit Status

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

Integer overflow vulnerabilities typically require specific conditions to trigger but can be exploited remotely

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: v2.23-rc2 and later

Vendor Advisory: https://github.com/Ralim/IronOS/pull/2083

Restart Required: Yes

Instructions:

1. Download latest IronOS firmware from official repository
2. Flash firmware to device using appropriate programming tools
3. Verify successful update and restart device

🔧 Temporary Workarounds

Network segmentation

all

Isolate IronOS devices from untrusted networks

Access control restrictions

all

Limit network access to IronOS devices to authorized users only

🧯 If You Can't Patch

  • Disconnect vulnerable devices from network entirely
  • Implement strict firewall rules to block all inbound traffic to affected devices

🔍 How to Verify

Check if Vulnerable:

Check IronOS firmware version on device via device interface or programming tool

Check Version:

Device-specific command via programming interface or device menu

Verify Fix Applied:

Confirm firmware version is v2.23-rc2 or later after update

📡 Detection & Monitoring

Log Indicators:

  • Unexpected device crashes
  • Memory allocation errors
  • Firmware version mismatch alerts

Network Indicators:

  • Unusual network traffic to/from IronOS devices
  • Connection attempts to device programming ports

SIEM Query:

source="ironos_device" AND (event_type="crash" OR event_type="memory_error")
