It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-16524 in the wild and no public exploit code.\n\nAffected product: Red Hat Enterprise Linux 10. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-16524/ (Markdown: https://insights.sbomify.com/CVE-2026-16524/index.md)","id":"CVE-2026-16524","markdown":"https://insights.sbomify.com/CVE-2026-16524/index.md","name":"CVE-2026-16524","record":{"aliases":["AZL-94377","DEBIAN-CVE-2026-16524","GHSA-f5qw-jg2q-vf56","UBUNTU-CVE-2026-16524"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux Performance Co-Pilot","requires_auth":"low_privilege","summary":"Attackers can execute arbitrary commands as the PMDA user via malicious shell metacharacters in the network.persocket.filter metric.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"A command injection flaw in PCP's linux_sockets PMDA allows malicious shell metacharacters via the network.persocket.filter metric.\nThis failed validation lets attackers execute arbitrary commands as the PMDA user when metrics refresh.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Pcp: pcp linux_sockets pmda: arbitrary command execution via command injection","id":"CVE-2026-16524","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2026"},"n_packages":0,"n_references":12,"next":{"headline":"Pcp: pcp: privilege escalation to root via linux_sockets pmda vulnerability","id":"CVE-2026-16526"},"packages":[],"prev":{"headline":"Supermicro BMC's syslog feature contains a command injection vulnerability","id":"CVE-2026-16521"},"products":["Red Hat Enterprise Linux 10","Red Hat Enterprise Linux 10.0 Extended Update Support","Red Hat Enterprise Linux 6","Red Hat Enterprise Linux 7","Red Hat Enterprise Linux 8","Red Hat Enterprise Linux 8.4 Advanced Mission Critical Update Support","Red Hat Enterprise Linux 8.4 Extended Update Support Long-Life Add-On","Red Hat Enterprise Linux 8.6 Advanced Mission Critical Update Support","Red Hat Enterprise Linux 8.6 Extended Update Support Long-Life Add-On","Red Hat Enterprise Linux 8.8 Telecommunications Update Service","Red Hat Enterprise Linux 8.8 Update Services for SAP Solutions","Red Hat Enterprise Linux 9","Red Hat Enterprise Linux 9.2 Update Services for SAP Solutions","Red Hat Enterprise Linux 9.4 Update Services for SAP Solutions","Red Hat Enterprise Linux 9.6 Extended Update Support","Red Hat OpenShift Container Platform 4"],"published":"2026-07-30","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-12","vendors":["Red Hat"]},"summary":"Attackers can execute arbitrary commands as the PMDA user via malicious shell metacharacters in the network.persocket.filter metric.","url":"https://insights.sbomify.com/CVE-2026-16524/"}
