Red Hat Security Advisory: capstone security update
Two security vulnerabilities have been identified in the Capstone disassembly framework used in Red Hat Enterprise Linux 10.0 Extended Update Support. The first is a memory corruption issue caused by an unchecked vsnprintf return (CVE-2025-68114). The second is a heap buffer overflow triggered via the skipdata callback, which 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 affected packages.
AI Analysis
Technical Summary
Capstone, a disassembly framework for binary analysis, contains two vulnerabilities affecting Red Hat Enterprise Linux 10.0 Extended Update Support. CVE-2025-68114 involves memory corruption due to an unchecked vsnprintf return value. CVE-2025-67873 is a heap buffer overflow vulnerability exploitable via the skipdata callback, potentially allowing denial of service or arbitrary code execution. Red Hat has issued a security advisory RHSA-2026:5224 with updated packages to fix these issues.
Potential Impact
The vulnerabilities can cause memory corruption and heap buffer overflow, which may result in denial of service or arbitrary code execution on affected systems running vulnerable versions of Capstone in Red Hat Enterprise Linux 10.0 Extended Update Support. This could allow attackers to disrupt services or execute malicious code with the privileges of the vulnerable application.
Mitigation Recommendations
Red Hat has released updated Capstone packages for Red Hat Enterprise Linux 10.0 Extended Update Support to address these vulnerabilities. Users should apply the security update as described in Red Hat advisory RHSA-2026:5224 and the referenced article https://access.redhat.com/articles/11258.
