CVE-2019-15875

Kernel data disclosure via core dump

Published Feb 18, 2020 · Updated Aug 5, 2024

Information disclosure in FreeBSD 12.1-STABLE before r354734 and earlier listed releases allows local users to read kernel data via core dumps. During crash handling, an incorrectly initialized stack data structure leaves up to 20 bytes of previously stored kernel bytes in the generated core file. A local user must trigger a process crash and obtain the resulting core dump; the documented consequence is limited confidentiality exposure without integrity or availability impact.
