Title: Linux Kernel 'pipe.c' Local Privilege Escalation Vulnerability

Severity: HIGH

Description:

Linux kernel is prone to a local privilege-escalation vulnerability that is caused by a NULL-pointer dereference. This issue occurs in the 'pipe_read_open()', 'pipe_write_open()', and 'pipe_rdwr_open()' functions of the 'pipe.c' source file. Specifically, when the mutex lock isn't held, the 'i_pipe' pointer could be released prematurely before it is used to update the pipe's reader or writer counters.

Local attackers can exploit this issue to execute arbitrary code with kernel-level privileges. Successful exploits will result in the complete compromise of affected computers. Failed exploit attempts will result in a denial-of-service condition.
