This vulnerability (CVE-2026-64749) involves a memory handling flaw in Apple iOS and iPadOS that could allow a malicious application to cause unexpected system termination or corrupt kernel memory. The flaw is classified under CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer). Apple fixed the issue in iOS 26.6 and iPadOS 26.6 by improving memory handling. The CVSS 3.1 vector indicates the attack requires local access with low complexity, no privileges, and user interaction, but results in high impact on confidentiality, integrity, and availability.

Exploitation of this vulnerability could lead to a malicious app causing the device to crash unexpectedly or corrupt kernel memory, potentially leading to system instability or compromise of sensitive kernel-level data. The high CVSS score reflects the potential for significant confidentiality, integrity, and availability impacts. However, no known exploits have been reported in the wild so far.

A fix is available in iOS 26.6 and iPadOS 26.6. Users and administrators should update affected devices to these versions or later to remediate this vulnerability. Since this is not a cloud service, remediation depends on applying the official software updates provided by Apple.
