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.

The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:3505-1 advisory.
