[原文]The asynchronous I/O facility in 4.4 BSD kernel does not check user credentials when setting the recipient of I/O notification, which allows local users to cause a denial of service by using certain ioctl and fcntl calls to cause the signal to be sent to an arbitrary process ID.

11062
Multiple BSD Kernel Asynchronous I/O Facility Notification DoS
Local Access Required Denial of Service, Input Manipulation, Misconfiguration
Loss of Integrity, Loss of Availability

- 漏洞描述

Certain BSD-derived kernels contain a flaw that may allow a local denial of service. The issue is triggered when a malicious user sends signals to arbitrary processes via certain ioctl and fcntl system calls to interrupt or kill processes, resulting in loss of availability for the service or platform.
