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 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 for multiple architectures. The update is rated with moderate security impact. No CVSS score is provided in the advisory.
AI Analysis
Technical Summary
Capstone, a disassembly framework used for binary analysis and reversing, contains two vulnerabilities: CVE-2025-68114 involves memory corruption due to an unchecked vsnprintf return value, and CVE-2025-67873 involves a heap buffer overflow triggered via the skipdata callback, which can result in denial of service or arbitrary code execution. These vulnerabilities affect Red Hat Enterprise Linux 10.0 Extended Update Support and related CodeReady Linux Builder packages across multiple CPU architectures. Red Hat has issued a security advisory (RHSA-2026:5224) and released updated capstone packages (version 5.0.1-7.el10_0) to fix these issues.
Potential Impact
The memory corruption vulnerability (CVE-2025-68114) can lead to unstable behavior or crashes. The heap buffer overflow vulnerability (CVE-2025-67873) is more severe, potentially allowing an attacker to cause denial of service or execute arbitrary code. Both vulnerabilities pose a risk to systems running affected versions of capstone, especially in environments where untrusted input is processed by the disassembly framework.
Mitigation Recommendations
Red Hat has released updated capstone packages (version 5.0.1-7.el10_0) that fix these vulnerabilities. Users of Red Hat Enterprise Linux 10.0 Extended Update Support and related CodeReady Linux Builder packages should apply the security update as described in Red Hat advisory RHSA-2026:5224 and the article https://access.redhat.com/articles/11258. No additional mitigations are specified or required beyond applying the official update.
