Technical detail
From CISA
Linux Kernel contains an integer overflow vulnerability in the create_elf_tables() function which could allow an unprivileged local user with access to SUID (or otherwise privileged) binary to escalate their privileges on the system.
This vulnerability affects a common open-source component, third-party library, or a protocol used by different products. Please check with specific vendors for information on patching status. For more information, please see: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/about/ ; https://www.kernel.org/ ; https://www.cve.org/CVERecord?id=CVE-2018-14634 ; https://access.redhat.com/errata/RHSA-2018:3540 ; https://nvd.nist.gov/vuln/detail/CVE-2018-14634
