Red Hat Enterprise Linux 10: denial of service

Medium6.5CVE-2026-16530 · Published Jul 30, 2026 · updated Aug 21, 2026

A flaw was found in the PCP (Performance Co-Pilot) `pmproxy` service. A remote attacker can exploit a vulnerability in the `pmLogLoadInDom()` function by sending a specially crafted request. This bypasses a critical bounds check, which can lead to the `pmproxy` service crashing, causing a Denial of Service (DoS). Additionally, this flaw may enable the leakage of sensitive information from the system's memory.
