CVE-2018-11508 is a local information disclosure vulnerability in the Linux kernel, specifically affecting the compat_get_timex function in kernel/compat.c. This flaw allows local users to extract sensitive information from kernel memory via the adjtimex system call, impacting various Linux distributions including Canonical and generic Linux kernels before version 4.16.9. Rated Medium severity (CVSS 5.5), this vulnerability requires local access (AV:L) with low attack complexity (AC:L) and no user interaction (UI:N), leading to high confidentiality impact (C:H) by leaking kernel pointers. There is no integrity or availability impact. While not listed on the CISA KEV catalog and currently inactive on the Hot List, an ExploitDB entry (EDB-46208) exists, indicating public exploit code availability. Despite this, there is minimal community discussion or media coverage surrounding this CVE.
