description

Linksys EA8100 firmware 1.0.3.216940 is affected in the SMB Service initialization script. A remote attacker may trigger improper initialization by manipulating an SMB-related argument when the affected service is reachable.

Still under analysis: more detail becomes available as the pipeline runs.

mitigation

Disable SMB Service if it is not required, or restrict access to trusted internal networks. No fixed version is recorded; monitor Linksys support channels for an updated firmware release.
