The fsidd daemon improperly handles input received over its local domain socket by relying on program assertions to verify command arguments. A local user can exploit this vulnerability by sending a malformed request lacking the required arguments to trigger an assertion failure. This causes the daemon to crash, resulting in a Denial of Service (DoS) for filesystem identifier lookup services until restarted.","epss":{"date":"2026-11-05","percentile":0.03946,"score":0.00147},"exploits":[{"kind":"exploit","source":"ADP: CISA-ADP","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2469511"}],"kev":null,"metrics":[{"score":5.5,"severity":"medium","source":"CNA: redhat","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"}],"modifiedAt":1793927634145,"publishedAt":1792172601720,"references":[{"source":"CNA: redhat","tags":["vdb-entry","x_refsource_REDHAT"],"url":"https://access.redhat.com/security/cve/CVE-2026-89098"},{"source":"CNA: redhat","tags":["issue-tracking","x_refsource_REDHAT"],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2469511"},{"source":"ADP: CISA-ADP","tags":["exploit"],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2469511"}],"remediation":[],"revision":"1b2d02a5baca4f68d5dac098008f388756989faf3374fe575eb1d4bfdbd0cc18","sources":[{"modifiedAt":1793927634145,"name":"CNA: redhat","retrievedAt":1793931068808,"url":"https://www.cve.org/CVERecord?id=CVE-2026-89098"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1793931087578,"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-89098"}],"ssvc":{"assessedAt":1792419363828,"automatable":"no","exploitation":"poc","source":"ADP: CISA-ADP","technicalImpact":"partial"},"status":"published","title":"Nfs-utils: nfs-utils: denial of service via assertion failure in fsidd","updatedAt":1793931087578}
