Detail

The uipc system calls (uipc_syscalls.c) in OpenBSD 2.9 and 3.0 provide user mode return instead of versus rval kernel mode values to the fdrelease function, which allows local users to cause a denial of service and trigger a null dereference.

Id Description
20354 OpenBSD uipc System Calls Null Dereference Local DoS

OpenBSD contains a flaw that may allow a local denial of service. The issue is triggered when a malicious attacker causes the sys_pipe() function to encounter a certain file descriptor error. This will cause sys_pipe() to dereference the user mode retval value instead of the rval kernel mode value. As retval is NULL, this will result in loss of availability for the platform.
