Summary

pcp security update

Details

Performance Co-Pilot (PCP) provides a framework and services to support system-level performance monitoring and performance management.

Security Fix(es):

A command injection flaw in PCP's linux_sockets PMDA allows malicious shell metacharacters via the network.persocket.filter metric. This failed validation lets attackers execute arbitrary commands as the PMDA user when metrics refresh.(CVE-2026-16524)

A flaw in the PCP linux_sockets module exposes an unsecured internal connection. An attacker with initial code execution can exploit this to escalate privileges and execute arbitrary commands as root.(CVE-2026-16526)

An unauthenticated remote attacker can bypass access controls by sending crafted requests to the PCP pmproxy /store endpoint. This allows the attacker to overwrite any PMDA metric, leading to arbitrary code execution and system takeover.(CVE-2026-16527)

A signed integer overflow in the PCP __pmGetPDU() function can be exploited via crafted network packets during PDU processing or SASL negotiation. This permanently blinds the affected daemon, resulting in a total denial of service (DoS) for subsequent packet reads.(CVE-2026-16529)

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.(CVE-2026-16530)
