Red Hat Security Advisory: capstone security update
Two security vulnerabilities have been identified in the Capstone disassembly framework used in Red Hat Enterprise Linux 9.6 Extended Update Support and related products. The first vulnerability (CVE-2025-68114) involves memory corruption due to an unchecked vsnprintf return. The second vulnerability (CVE-2025-67873) is a heap buffer overflow via the skipdata callback, which can lead to denial of service or arbitrary code execution. Red Hat has released an update to address these issues in version 4.0.2-11.el9_6 of the capstone package.
AI Analysis
Technical Summary
Capstone is a disassembly framework aimed at binary analysis and reversing. Two vulnerabilities were found: CVE-2025-68114, a memory corruption issue caused by an unchecked vsnprintf return, and CVE-2025-67873, a heap buffer overflow triggered via the skipdata callback. These vulnerabilities can result in denial of service or arbitrary code execution. Red Hat has issued a security advisory (RHSA-2026:5124) providing updated capstone packages for Red Hat Enterprise Linux 9.6 Extended Update Support and related variants to fix these issues.
Potential Impact
The vulnerabilities allow an attacker to cause memory corruption or heap buffer overflow, which can lead to denial of service or arbitrary code execution on affected systems running vulnerable versions of capstone. This poses a moderate security risk as rated by Red Hat Product Security.
Mitigation Recommendations
Red Hat has released updated capstone packages (version 4.0.2-11.el9_6) that fix these vulnerabilities. Users of Red Hat Enterprise Linux 9.6 Extended Update Support and related products should apply the updates as described in Red Hat advisory RHSA-2026:5124 and the referenced article https://access.redhat.com/articles/11258.
