CVE-2010-4012: Race condition in Apple iOS 4.0 through 4.1 for iPhone 3G and later allows physically proximate attackers t...

Security readout for executives and security teams

This is a passcode lock bypass in very old Apple iOS releases. A person with physical access to an affected iPhone could get past the lock screen through a race condition involving emergency-call handling and the sleep/wake transition. Exposure is likely limited to legacy iPhones running iOS 4.0 or 4.1. Modern fleets are unlikely to be affected unless old devices remain in storage, labs, point-of-sale use, or unmanaged bring-your-own-device scenarios. Treat this as a legacy-device hygiene issue, not a current widespread emergency. Prioritize finding and retiring affected iPhones if they can access business data or regulated information. Mitigation focus: Inventory iPhones for iOS 4.0 or 4.1 exposure.; Review Apple advisory HT4456 for vendor remediation guidance.; Retire or replace devices that cannot leave affected versions..
