Summary
Package updates are available for Amazon Linux 2023 that fix the following vulnerabilities: CVE-2026-19617: A flaw was found in libdm. A remote attacker could craft a malicious Logical Volume Manager (LVM) metadata configuration with deeply nested structures. This could lead to uncontrolled recursion in the libdm configuration file parser, exhausting the stack and causing any LVM command reading the metadata to crash. This vulnerability results in a Denial of Service (DoS) for affected systems.
