Denial of Service Vulnerability in Linux Kernel Prior to Version 4.17

CVE-2018-1120 · LOW Severity

AV:N/AC:M/AU:S/C:N/I:N/A:P

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).
