{"cve":"CVE-2023-6917","nvd":{"published":"2024-02-28T15:15:07.867","modified":"2026-06-17T06:51:40.807","status":"Modified","description":"A vulnerability has been identified in the Performance Co-Pilot (PCP) package, stemming from the mixed privilege levels utilized by systemd services associated with PCP. While certain services operate within the confines of limited PCP user/group privileges, others are granted full root privileges. This disparity in privilege levels poses a risk when privileged root processes interact with directories or directory trees owned by unprivileged PCP users. Specifically, this vulnerability may lead to the compromise of PCP user isolation and facilitate local PCP-to-root exploits, particularly through symlink attacks. These vulnerabilities underscore the importance of maintaining robust privilege separation mechanisms within PCP to mitigate the potential for unauthorized privilege escalation.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","score":6.7},"cwes":["CWE-367"],"references":["https://access.redhat.com/errata/RHSA-2024:2213","https://access.redhat.com/security/cve/CVE-2023-6917","https://bugzilla.redhat.com/show_bug.cgi?id=2254983","https://access.redhat.com/errata/RHSA-2024:2213","https://access.redhat.com/security/cve/CVE-2023-6917"],"products":["redhat:enterprise_linux","sgi:performance_co-pilot"],"source":"nvd","synced_at":"2026-10-19T21:45:59.823092188+00:00"},"epss":{"cve":"CVE-2023-6917","score":0.00202,"percentile":0.10136,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
