An update for pcp is now available for openEuler-24.03-LTS-SP4 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2026-3809 Final 1.0 1.0 2026-09-14 Initial 2026-09-14 2026-09-14 openEuler SA Tool V1.0 2026-09-14 pcp security update An update for pcp is now available for openEuler-24.03-LTS-SP4 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) An update for pcp is now available for openEuler-24.03-LTS-SP4. openEuler Security has rated this update as having a security impact of high. A Common Vunlnerability Scoring System(CVSS)base score,which gives a detailed severity rating, is available for each vulnerability from the CVElink(s) in the References section.

This allows the attacker to overwrite any PMDA metric, leading to arbitrary code execution and system takeover. 2026-09-14 CVE-2026-16527 openEuler-24.03-LTS-SP4 High 7.3 AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L pcp security update 2026-09-14 https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-3809 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. 2026-09-14 CVE-2026-16529 openEuler-24.03-LTS-SP4 High 7.5 AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H pcp security update 2026-09-14 https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-3809 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. 2026-09-14 CVE-2026-16530 openEuler-24.03-LTS-SP4 Medium 6.5 AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L pcp security update 2026-09-14 https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-3809
