CVE-2018-1120 is a denial-of-service vulnerability affecting the Linux kernel before version 4.17, specifically impacting utilities like ps and w from psutils or procps, as well as other programs reading /proc/<pid>/cmdline or /proc/<pid>/environ files. An attacker can exploit this by mapping a FUSE-backed file into a process's memory containing command-line arguments or environment strings, causing these utilities to block indefinitely. With a CVSS score of 5.3 (MEDIUM), this vulnerability has a network attack vector and high attack complexity, leading to a denial of service. There is no evidence of active exploitation, though an exploit (EDB-44806) exists for procps-ng, and it has received minimal community discussion or media coverage.
