Red Hat Security Advisory: capstone security update
Two security vulnerabilities have been identified in the Capstone disassembly framework used in Red Hat Enterprise Linux 9.0. These include a memory corruption issue caused by an unchecked vsnprintf return (CVE-2025-68114) and a heap buffer overflow via the skipdata callback (CVE-2025-67873). The heap buffer overflow can lead to denial of service or arbitrary code execution. Red Hat has released an update to address these issues in the capstone package version 4.0.2-5.el9_0 for multiple architectures. The update is rated as having a moderate security impact.
