CVE-2025-24302
📋 TL;DR
This vulnerability in Intel's TinyCBOR libraries allows authenticated users to trigger uncontrolled recursion, potentially leading to privilege escalation through local access. It affects systems using vulnerable versions of Intel-maintained TinyCBOR libraries. The issue requires local authenticated access to exploit.

⚠️ Risk & Real-World Impact
Worst Case
An authenticated attacker could escalate privileges to gain root/system-level access on the affected system, potentially compromising the entire host.
Likely Case
An authenticated user with limited privileges could gain elevated permissions, allowing them to access restricted data or perform unauthorized actions.
If Mitigated
With proper access controls and patching, the risk is limited to authenticated users who already have some level of system access.
🎯 Exploit Status
Exploitation requires local authenticated access and knowledge of the vulnerable library's usage patterns.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 0.6.1 or later
Vendor Advisory: https://intel.com/content/www/us/en/security-center/advisory/intel-sa-01326.html
Restart Required: No
Instructions:
1. Identify systems using Intel TinyCBOR library. 2. Update to version 0.6.1 or later. 3. Recompile applications using the library. 4. Deploy updated applications.
🔧 Temporary Workarounds
Restrict local user access
allLimit which users have local authenticated access to systems using vulnerable TinyCBOR libraries
Implement privilege separation
allRun applications using TinyCBOR with minimal necessary privileges
🧯 If You Can't Patch
- Implement strict access controls to limit which users can access systems with vulnerable libraries
- Monitor for unusual privilege escalation attempts and review user activity logs
🔍 How to Verify
Check if Vulnerable:
Check TinyCBOR library version in use. If version is below 0.6.1, the system is vulnerable.Check Version:
Check library version through package manager or by examining library filesVerify Fix Applied:
Verify TinyCBOR library version is 0.6.1 or higher after update📡 Detection & Monitoring
