This input validation vulnerability allows a local attacker, by sending specially crafted service lookup requests to the NSS responder's UNIX socket, to cause an out-of-bounds read. This out-of-bounds read may lead to a denial of service (DoS) by crashing the NSS responder process. While unprivileged local clients can typically reach the socket, there is no evidence of privilege escalation or reliable data disclosure.","epss":{"date":"2026-11-06","percentile":0.04181,"score":0.0015},"exploits":[],"kev":null,"metrics":[{"score":4,"severity":"medium","source":"CNA: redhat","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"}],"modifiedAt":1793994971179,"publishedAt":1789399261029,"references":[{"source":"CNA: redhat","tags":["vdb-entry","x_refsource_REDHAT"],"url":"https://access.redhat.com/security/cve/CVE-2026-90463"},{"source":"CNA: redhat","tags":["issue-tracking","x_refsource_REDHAT"],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2479268"}],"remediation":[{"kind":"workaround","source":"CNA: redhat","text":"There's no appropriated mitigation for this issue."}],"revision":"89579984c2964384b2f93eb3ef7c366179e5e7d380bef8daeff8309f1697de97","sources":[{"modifiedAt":1793994971179,"name":"CNA: redhat","retrievedAt":1793995903099,"url":"https://www.cve.org/CVERecord?id=CVE-2026-90463"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1793995927836,"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-90463"}],"ssvc":{"assessedAt":1789404301031,"automatable":"no","exploitation":"none","source":"ADP: CISA-ADP","technicalImpact":"partial"},"status":"published","title":"Sssd: local oob read in nss service request parsers (`sss_nss_protocol_parse_svc_name` / `sss_nss_protocol_parse_svc_port`)","updatedAt":1793995927836}
