CVE-2005-3359: The atm module in Linux kernel 2.6 before 2.6.14 allows local users to cause a denial of service (panic) vi...

Security readout for executives and security teams

This is an old Linux kernel denial-of-service issue. A user who can run code locally on an affected system may be able to crash the machine by triggering a flaw in the ATM networking module. The business impact is availability loss, not data theft, based on the provided sources. Exposure is most likely on legacy Linux 2.6 systems, vendor appliances, or embedded platforms still carrying kernel code before 2.6.14 with ATM support present. Modern supported distributions are unlikely to be affected unless they include very old kernels or backported vulnerable code. Prioritize remediation for legacy systems that still support local user access or shared operational workloads. This is not evidenced as internet-exploitable, but a crash on critical infrastructure can still create business disruption. Mitigation focus: Identify systems running Linux kernel 2.6 before 2.6.14.; Apply vendor-supported kernel updates from relevant distribution advisories.; Check Avaya or appliance vendor guidance for bundled affected kernels..
