Red Hat Security Advisory: capstone security update
Capstone is a disassembly framework with the target of becoming the ultimate disasm engine for binary analysis and reversing in the security community. Security Fix(es): * capstone: Capstone: Memory corruption via unchecked vsnprintf return (CVE-2025-68114) * capstone: Capstone: Heap buffer overflow via skipdata callback allows denial of service or arbitrary code execution. (CVE-2025-67873) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
AI Analysis
Technical Summary
The Capstone disassembly framework included in Red Hat Enterprise Linux 9.6 Extended Update Support and related products contains two security vulnerabilities. CVE-2025-68114 is a memory corruption issue resulting from an unchecked return value of vsnprintf, which can lead to memory corruption. CVE-2025-67873 is a heap buffer overflow triggered via the skipdata callback, potentially allowing denial of service or arbitrary code execution. Red Hat has issued a security advisory RHSA-2026:5124 providing updated Capstone packages (version 4.0.2-11.el9_6) that fix these vulnerabilities. The advisory covers multiple architectures and product variants. No exploits are known in the wild at this time. The vulnerabilities are rated as moderate severity by Red Hat. Users should apply the provided updates to remediate these issues.
Potential Impact
Successful exploitation of CVE-2025-67873 could allow an attacker to cause denial of service or execute arbitrary code due to a heap buffer overflow in the skipdata callback. CVE-2025-68114 could cause memory corruption due to an unchecked vsnprintf return value. Both vulnerabilities affect the Capstone framework used in Red Hat Enterprise Linux 9.6 Extended Update Support and related products. No known exploits are reported in the wild. The impact is rated moderate by Red Hat Product Security.
Mitigation Recommendations
Red Hat has released updated Capstone packages (version 4.0.2-11.el9_6) that address these vulnerabilities. Users of affected Red Hat Enterprise Linux 9.6 Extended Update Support and CodeReady Linux Builder 9.6 should apply these security updates promptly. Detailed update instructions are available at https://access.redhat.com/articles/11258. No additional mitigation steps are indicated by the vendor advisory.
