CVE-2012-3412: The sfc (aka Solarflare Solarstorm) driver in the Linux kernel before 3.2.30 allows remote attackers to cau...

Security readout for executives and security teams

This vulnerability can let a remote attacker knock affected Linux systems off the network by sending crafted TCP traffic. It is limited to systems using the Solarflare Solarstorm sfc network driver on vulnerable kernels before the fix. The known impact is denial of service, not data theft or code execution. Exposure is most likely on older Linux systems using Solarflare Solarstorm network adapters with the sfc driver and unpatched kernels or vendor kernel packages. Systems without that driver or hardware are unlikely to be affected based on the provided description. Prioritize remediation where legacy Linux systems use Solarflare sfc network hardware in business-critical or internet-exposed roles. The issue is not described as data-compromising, but it can create service outages and should be handled through normal kernel patch governance. Mitigation focus: Upgrade to a kernel containing the sfc fix, including Linux 3.2.30 or vendor-patched packages.; Apply relevant Ubuntu, Red Hat, SUSE, or upstream kernel updates where applicable.; Inventory hosts using Solarflare Solarstorm adapters and the sfc driver..
