{"id":"OESA-2026-3808","summary":"pcp security update","details":"Performance Co-Pilot (PCP) provides a framework and services to support system-level performance monitoring and performance management.\r\n\r\nSecurity Fix(es):\n\nA 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)\n\nA 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)\n\nAn 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)\n\nA 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)\n\nA 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)","modified":"2026-09-13T16:45:40.725355434Z","published":"2026-09-14T16:34:34Z","upstream":["CVE-2026-16524","CVE-2026-16526","CVE-2026-16527","CVE-2026-16529","CVE-2026-16530"],"database_specific":{"severity":"High"},"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-3808"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-16524"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-16526"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-16527"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-16529"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-16530"}],"affected":[{"package":{"name":"pcp","ecosystem":"openEuler:24.03-LTS-SP1","purl":"pkg:rpm/openEuler/pcp&distro=openEuler-24.03-LTS-SP1"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.2.2-7.oe2403sp1"}]}],"ecosystem_specific":{"aarch64":["pcp-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-conf-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-debuginfo-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-debugsource-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-devel-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-export-pcp2elasticsearch-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-export-pcp2graphite-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-export-pcp2influxdb-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-export-pcp2json-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-export-pcp2openmetrics-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-export-pcp2spark-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-export-pcp2xml-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-export-pcp2zabbix-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-export-zabbix-agent-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-geolocate-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-gui-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-import-collectl2pcp-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-import-ganglia2pcp-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-import-iostat2pcp-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-import-mrtg2pcp-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-import-sar2pcp-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-libs-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-libs-devel-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-activemq-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-apache-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-bash-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-bcc-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-bind2-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-bonding-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-bpf-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-bpftrace-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-cifs-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-cisco-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-dbping-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-denki-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-dm-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-docker-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-ds389-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-ds389log-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-elasticsearch-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-farm-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-gfs2-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-gluster-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-gpfs-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-gpsd-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-hacluster-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-haproxy-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-infiniband-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-json-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-libvirt-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-lio-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-lmsensors-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-logger-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-lustre-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-lustrecomm-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-mailq-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-memcache-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-mic-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-mongodb-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-mounts-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-mysql-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-named-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-netcheck-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-netfilter-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-news-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-nfsclient-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-nginx-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-nutcracker-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-nvidia-gpu-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-openmetrics-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-openvswitch-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-oracle-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-pdns-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-perfevent-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-podman-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-postfix-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-postgresql-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-rabbitmq-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-redis-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-roomtemp-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-rsyslog-6.2.2-7.oe2403sp1.aarch64.rpm","pcp-pmda-samb
