CVE-2011-3259: The kernel in Apple iOS before 5 and Apple TV before 4.4 does not properly recover memory allocated for inc...

Security readout for executives and security teams

This flaw lets a remote attacker exhaust kernel memory on older Apple iOS and Apple TV devices by causing many incomplete TCP connections. The business impact is availability: affected devices could become unstable or unavailable. It is not described as data theft or code execution in the provided sources. Exposure is limited to legacy Apple iOS devices running versions before iOS 5 and Apple TV devices running versions before 4.4. Modern environments should mainly treat this as an inventory and retirement risk unless old devices remain network-connected. Low for most current environments, but moderate where legacy Apple devices remain reachable. Prioritize discovery and removal from production networks because unsupported devices can create avoidable availability risk even when the vulnerability is old. Mitigation focus: Identify any iOS devices below version 5 and Apple TV devices below version 4.4.; Update affected devices according to Apple guidance where supported.; Retire or isolate devices that cannot be updated..
