Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-16526 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-2026-16526/ (Markdown: https://insights.sbomify.com/CVE-2026-16526/index.md)","id":"CVE-2026-16526","markdown":"https://insights.sbomify.com/CVE-2026-16526/index.md","name":"CVE-2026-16526","record":{"aliases":["AZL-94380","DEBIAN-CVE-2026-16526","GHSA-534w-2xfq-h655","UBUNTU-CVE-2026-16526"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["privilege_escalation","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux Performance Co-Pilot","requires_auth":"low_privilege","summary":"An attacker with local access can exploit an unsecured internal connection in the PCP linux_sockets module to escalate privileges to root.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-403","name":"Exposure of File Descriptor to Unintended Control Sphere"}],"description":"A flaw in the PCP linux_sockets module exposes an unsecured internal connection.\nAn attacker with initial code execution can exploit this to escalate privileges and execute arbitrary commands as root.","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: privilege escalation to root via linux_sockets pmda vulnerability","id":"CVE-2026-16526","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"privilege_escalation","year":"2026"},"n_packages":0,"n_references":12,"next":{"headline":"Pcp: pcp pmproxy: unauthenticated access to /store endpoint allows bypassing pmcd access rules","id":"CVE-2026-16527"},"packages":[],"prev":{"headline":"Pcp: pcp linux_sockets pmda: arbitrary command execution via command injection","id":"CVE-2026-16524"},"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":"2026-10-01","vendors":["Red Hat"]},"summary":"An attacker with local access can exploit an unsecured internal connection in the PCP linux_sockets module to escalate privileges to root.","url":"https://insights.sbomify.com/CVE-2026-16526/"}
