Red Hat Security Advisory: capstone security update
Two vulnerabilities have been identified in the Capstone disassembly framework used in Red Hat Enterprise Linux 9.2. The first is a memory corruption issue caused by an unchecked vsnprintf return (CVE-2025-68114). The second is a heap buffer overflow via the skipdata callback that can lead to denial of service or arbitrary code execution (CVE-2025-67873). Red Hat has released an update to address these issues in the capstone package version 4.0.2-11.el9_2. The security impact is rated as moderate by Red Hat Product Security.
