When Identity Provider (IdP) authentication is enabled, pre-authentication requests retain state in memory without being cleared or timed out. A local attacker can repeatedly initiate authentication flows without completing them, causing unbounded memory consumption. This memory exhaustion can lead to a Denial of Service (DoS) by degrading or terminating SSSD authentication services.","epss":{"date":"2026-11-05","percentile":0.05235,"score":0.0016},"exploits":[{"kind":"exploit","source":"secalert@redhat.com","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2478662"}],"kev":null,"metrics":[{"score":6.2,"severity":"medium","source":"CNA: redhat","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},{"score":6.2,"severity":"medium","source":"NVD: secalert@redhat.com","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"}],"modifiedAt":1793895448873,"publishedAt":1791316986080,"references":[{"source":"CNA: redhat","tags":["vdb-entry","x_refsource_REDHAT"],"url":"https://access.redhat.com/security/cve/CVE-2026-104046"},{"source":"CNA: redhat","tags":["issue-tracking","x_refsource_REDHAT"],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2478662"},{"source":"secalert@redhat.com","tags":["Vendor Advisory"],"url":"https://access.redhat.com/security/cve/CVE-2026-104046"},{"source":"secalert@redhat.com","tags":["Exploit","Issue Tracking","Mitigation","Vendor Advisory"],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2478662"}],"remediation":[{"kind":"workaround","source":"CNA: redhat","text":"Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability."}],"revision":"5b3bf32d0cdf0f98c2146a21bd5e5aab1ce067940b4213bc9934564c7003b5d1","sources":[{"modifiedAt":1793893986973,"name":"CNA: redhat","retrievedAt":1793895247797,"url":"https://www.cve.org/CVERecord?id=CVE-2026-104046"},{"modifiedAt":1793895448873,"name":"NVD","retrievedAt":1793902860008,"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-104046"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1793895248298,"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-104046"}],"ssvc":{"assessedAt":1791510305929,"automatable":"no","exploitation":"none","source":"ADP: CISA-ADP","technicalImpact":"partial"},"status":"published","title":"Sssd: sssd: denial of service via incomplete identity provider authentication requests","updatedAt":1793902860008}
