Security readout for executives and security teams
Plain-English summary
CVE-2025-60692 is a memory-safety flaw reported in Cisco Linksys E1200 v2 router firmware. A local attacker able to influence ARP table contents could crash the device or potentially run code. The public sources do not show confirmed exploitation or a vendor fix.
Executive priority
Treat this as high priority for any remaining E1200 v2 routers, especially in sensitive networks. The urgency is lower than internet-exploited flaws because sources describe local exploitation and no KEV listing, but obsolete edge devices should be remediated or replaced quickly.
Technical view
The issue is a stack-based buffer overflow in libshared.so functions get_mac_from_ip and get_ip_from_mac. They parse /proc/net/arp with sscanf "%100s" into 50-byte stack buffers or subarrays, causing possible memory corruption. CVSS 3.1 is 8.4 with local attack vector.
Likely exposure
Exposure appears limited to environments running Linksys E1200 v2 firmware E1200_v2.0.11.001_us.tar.gz. The CVE record’s affected-product fields are incomplete, so confirm against actual router model, hardware version, and firmware version before scoping broadly.
Exploitation context
The source bundle says exploitation requires a local attacker controlling /proc/net/arp contents. CISA KEV is false in the bundle, and no cited source confirms active exploitation in the wild.
Researcher notes
The strongest technical evidence is the linked research note and CVE metadata. Official affected-product fields are listed as n/a, and the bundle provides no vendor patch details. Avoid assuming other Linksys models are affected without source confirmation.
Mitigation direction
- Check Linksys guidance for affected firmware status and fixed releases.
- Upgrade firmware if Linksys provides a corrected version.
- Restrict local administrative and network access to affected routers.
- Retire or replace unsupported E1200 v2 devices where practical.
- Monitor affected routers for unexpected crashes or resets.
Validation and detection
- Inventory deployed Linksys E1200 v2 routers and hardware revisions.
- Confirm whether firmware matches E1200_v2.0.11.001_us.tar.gz or version 2.0.11.001.
- Review Linksys advisories before declaring remediation complete.
- Check vulnerability records for updated affected-product or patch data.
- Look for unexplained router instability in device logs or monitoring.
