The service runs as root and operates on a file inside a directory owned by an unprivileged system user without verifying that the file is not a symbolic link. A local attacker who has already compromised the privileged yggdrasil system service account can exploit this to gain ownership of arbitrary files, leading to privilege escalation to root.","state":0,"publishedAt":"2026-10-19T11:39:13.59+00:00","modifiedAt":"2026-10-19T18:29:07.128+00:00","affected":[{"ecosystem":"https://access.redhat.com/downloads/content/package-browser/","name":"rhc","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Red Hat\",\n                    \"product\": \"Red Hat Enterprise Linux 10\",\n                    \"collectionURL\": \"https://access.redhat.com/downloads/content/package-browser/\",\n                    \"packageName\": \"rhc\",\n                    \"defaultStatus\": \"affected\",\n                    \"cpes\": [\n                        \"cpe:/o:redhat:enterprise_linux:10\"\n                    ]\n                }"},{"ecosystem":"https://access.redhat.com/downloads/content/package-browser/","name":"rhc","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Red Hat\",\n                    \"product\": \"Red Hat Enterprise Linux 7\",\n                    \"collectionURL\": \"https://access.redhat.com/downloads/content/package-browser/\",\n                    \"packageName\": \"rhc\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"cpes\": [\n                        \"cpe:/o:redhat:enterprise_linux:7\"\n                    ]\n                }"},{"ecosystem":"https://access.redhat.com/downloads/content/package-browser/","name":"rhc","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Red Hat\",\n                    \"product\": \"Red Hat Enterprise Linux 8\",\n                    \"collectionURL\": \"https://access.redhat.com/downloads/content/package-browser/\",\n                    \"packageName\": \"rhc\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"cpes\": [\n                        \"cpe:/o:redhat:enterprise_linux:8\"\n                    ]\n                }"},{"ecosystem":"https://access.redhat.com/downloads/content/package-browser/","name":"rhc","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Red Hat\",\n                    \"product\": \"Red Hat Enterprise Linux 9\",\n                    \"collectionURL\": \"https://access.redhat.com/downloads/content/package-browser/\",\n                    \"packageName\": \"rhc\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"cpes\": [\n                        \"cpe:/o:redhat:enterprise_linux:9\"\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:H/A:H","score":6,"severity":"MEDIUM"}],"references":["https://access.redhat.com/security/cve/CVE-2026-112210","https://bugzilla.redhat.com/show_bug.cgi?id=2555474","https://github.com/RedHatInsights/rhc/blob/51928db/data/systemd/rhc-canonical-facts.service"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-112210","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-112210","identifiers":["CVE-2026-112210"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
