When the mutex lock is not held, the i_pipe pointer could + be released by other processes before it is used to update the pipe's reader + and writer counters. This could lead to a local denial of service or + privilege escalation. +References: + http://www.openwall.com/lists/oss-security/2009/11/03/1 +Notes: + Brad Spengler *claims* to have already developed a working exploit. Since + his previous work has been effective, it is probably true.
