AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
A remote attacker can cause a denial of service on Apple iOS devices before 7 by sending an invalid packet fragment, triggering a kernel assertion failure and device restart.
Vulnerability
The kernel in Apple iOS versions prior to 7 contains a flaw in handling network packet fragments. An invalid packet fragment can trigger an assertion failure in the kernel, leading to a system restart. Affected versions: iOS before 7.
Exploitation
An attacker can send a specially crafted invalid packet fragment over the network to a vulnerable iOS device. No authentication or user interaction is required. The packet fragment is processed by the kernel, causing the assertion failure.
Impact
Successful exploitation results in a denial of service, causing the device to restart. This can disrupt device availability and potentially lead to loss of unsaved data.
Mitigation
Apple addressed this issue in iOS 7, released on September 18, 2013 [1]. Users should update to iOS 7 or later via device settings or iTunes. No workarounds are documented. The vulnerability is not listed on CISA's Known Exploited Vulnerabilities (KEV) catalog.
