Red Hat Security Advisory: capstone security update
Two security vulnerabilities have been identified in the Capstone disassembly framework used in Red Hat Enterprise Linux 9.4 Extended Update Support and related products. The first vulnerability (CVE-2025-68114) involves memory corruption caused by an unchecked vsnprintf return. The second vulnerability (CVE-2025-67873) is a heap buffer overflow triggered via the skipdata callback, which can lead to denial of service or arbitrary code execution. Red Hat has released updated packages to address these issues.
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 due to an unchecked vsnprintf return, and CVE-2025-67873, a heap buffer overflow via the skipdata callback. These flaws can cause denial of service or enable arbitrary code execution. Red Hat issued a security advisory (RHSA-2026:5125) providing updated packages for Red Hat Enterprise Linux 9.4 Extended Update Support and related variants to fix these vulnerabilities.
Potential Impact
The heap buffer overflow vulnerability (CVE-2025-67873) can allow an attacker to cause denial of service or execute arbitrary code, potentially compromising system integrity. The memory corruption vulnerability (CVE-2025-68114) may also lead to instability or exploitation. Both vulnerabilities pose moderate security risks as rated by Red Hat.
Mitigation Recommendations
