Summary
pacemaker security update
Details

Pacemaker is an advanced, scalable High-Availability cluster resource manager.

Security Fix(es):

A flaw was found in Pacemaker. An unauthenticated remote attacker can exploit an integer overflow vulnerability in the remote message decompression process. By sending a specially crafted compressed remote message before authentication, an attacker can cause memory corruption, leading to a denial of service (DoS) in the CIB remote listener. This can result in the affected service crashing.(CVE-2026-10649)

Severity
