In FreeBSD before 11.1-STABLE(r332303), 11.1-RELEASE-p10, 10.4-STABLE(r332321), and 10.4-RELEASE-p9, due to insufficient initialization of memory copied to userland in the Linux subsystem and Atheros wireless driver, small amounts of kernel memory may be disclosed to userland processes. Unprivileged authenticated local users may be able to access small amounts of privileged kernel data.

Security readout for executives and security teams

CVE-2018-6920 is a FreeBSD kernel memory disclosure issue. A logged-in, unprivileged local user may be able to read small amounts of privileged kernel data through affected Linux subsystem or Atheros wireless driver paths. Exposure is most relevant on FreeBSD hosts with local user access, shell accounts, shared hosting, or workloads where untrusted authenticated users can run processes. Treat this as a moderate-priority hygiene fix, higher for shared FreeBSD environments. It is not shown as remotely exploitable or actively exploited in the supplied sources. Mitigation focus: Upgrade FreeBSD to the fixed release or stable revision named in the advisory.; Prioritize shared or multi-user FreeBSD systems where local users are not fully trusted.; Review FreeBSD advisory FreeBSD-EN-18:05.mem for vendor-specific patch instructions..
