CVE-2024-27826 is a vulnerability in Apple Neural Engine components of iOS, iPadOS, and macOS Ventura that allows a local attacker to cause unexpected system shutdowns. The root cause is related to improper memory handling which could be triggered by a local attacker with limited privileges and user interaction. Apple fixed this issue by improving memory handling in the affected software versions. The CVSS v3.1 base score is 7.8, indicating a high severity with attack vector local, low attack complexity, no privileges required, user interaction required, and impacts on confidentiality, integrity, and availability.

A local attacker with user interaction could cause an unexpected system shutdown on affected Apple devices running vulnerable versions of iOS, iPadOS, or macOS Ventura. This could disrupt device availability and potentially impact confidentiality and integrity due to the nature of the memory handling flaw. There are no known exploits in the wild at the time of disclosure.

Apple has released official patches addressing this vulnerability in iOS 17.5, iPadOS 17.5, and macOS Ventura 13.6.8. Users and administrators should apply these updates promptly to mitigate the risk. Since this is a local vulnerability requiring user interaction, applying the official updates is the primary and recommended mitigation. No additional vendor-advised mitigations are specified.
