CVE-2019-5605: FreeBSD vulnerability

CVE-2019-5605: In FreeBSD 11.3-STABLE before r350217, 11.3-RELEASE before 11.3-RELEASE-p1, and 11.2-RELEASE before 11.2-RE...

In FreeBSD 11.3-STABLE before r350217, 11.3-RELEASE before 11.3-RELEASE-p1, and 11.2-RELEASE before 11.2-RELEASE-p12, due to insufficient initialization of memory copied to userland in the freebsd32_ioctl interface, small amounts of kernel memory may be disclosed to userland processes. This may allow an attacker to leverage this information to obtain elevated privileges either directly or indirectly.

Security readout for executives and security teams

CVE-2019-5605 is a FreeBSD kernel information disclosure issue. A local userland process may receive small amounts of uninitialized kernel memory through the freebsd32_ioctl interface. That leak could help an attacker raise privileges, directly or as support for another weakness. Exposure is mainly FreeBSD 11.x systems before the fixed releases, especially where untrusted local users or processes can execute code. No source in the bundle establishes remote exploitability or affected non-FreeBSD products beyond linked advisory review needs. Treat this as a targeted kernel hygiene issue, not an internet-wide emergency. Patch affected FreeBSD 11.x systems promptly where local users, shared workloads, or exposed application compromise paths make privilege escalation meaningful. Mitigation focus: Upgrade FreeBSD 11.3-RELEASE to 11.3-RELEASE-p1 or later.; Upgrade FreeBSD 11.2-RELEASE to 11.2-RELEASE-p12 or later.; For 11.3-STABLE, update beyond revision r350217..
