CVE-2024-27815 is an out-of-bounds write vulnerability in the kernel component of Apple iOS and iPadOS. This flaw could allow a malicious app to execute arbitrary code with kernel privileges, potentially compromising system integrity. The issue was resolved by Apple through improved input validation and memory handling in iOS 17.5 and iPadOS 17.5. The CVSS v3.1 vector indicates network attack vector, high attack complexity, high privileges required, no user interaction, unchanged scope, and high confidentiality and integrity impact but no availability impact. Apple has officially released patches for this vulnerability as part of their May 13, 2024 security updates.

An attacker with an app running on a vulnerable iOS or iPadOS device could execute arbitrary code with kernel privileges, which may lead to a full compromise of the affected device's operating system security. The vulnerability impacts confidentiality and integrity but does not affect availability. No known exploits are currently reported in the wild.

Apple has released official patches for this vulnerability in iOS 17.5 and iPadOS 17.5. Users and administrators should update affected devices to these versions or later to remediate the issue. Since this is a local privilege escalation vulnerability requiring high privileges, applying the official update fully mitigates the risk. No additional mitigation actions are required beyond applying the official fix.
