K42202505 : Linux kernel vulnerability CVE-2018-1120

Security Advisory Description

A flaw was found affecting the Linux kernel before version 4.17. By mmap()ing a FUSE-backed file onto a process’s memory containing command line arguments (or environment strings), an attacker can cause utilities from psutils or procps (such as ps, w) or any other program which makes a read() call to the /proc/<pid>/cmdline (or /proc/<pid>/environ) files to block indefinitely (denial of service) or for some controlled time (as a synchronization primitive for other attacks). (CVE-2018-1120)

Impact

An attacker with local access may be able to cause a Denial of Service (DoS).
