{"id":"UBUNTU-CVE-2026-94640","details":"A flaw was found in rpcbind. This vulnerability allows a remote, unauthenticated attacker to cause a Denial of Service (DoS) by sending a large number of unique requests. The rpcbind service records previously unseen RPC (Remote Procedure Call) statistics in unbounded in-memory lists, leading to persistent memory growth and increased CPU usage. This can degrade or exhaust service availability.","modified":"2026-09-24T02:03:14.172804361Z","published":"2026-09-22T16:18:00Z","upstream":["CVE-2026-94640"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-94640"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-94640"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2462960"}],"affected":[{"package":{"name":"rpcbind","ecosystem":"Ubuntu:Pro:14.04:LTS","purl":"pkg:deb/ubuntu/rpcbind?arch=source&distro=esm-infra-legacy%2Ftrusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.2.0-8.2ubuntu2","0.2.1-2ubuntu1","0.2.1-2ubuntu2.1","0.2.1-2ubuntu2.2","0.2.1-2ubuntu2.2+esm1","0.2.1-2ubuntu2.2+esm2","0.2.1-2ubuntu2.2+esm3"],"ecosystem_specific":{"binaries":[{"binary_version":"0.2.1-2ubuntu2.2+esm3","binary_name":"rpcbind"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-94640.json"}},{"package":{"name":"rpcbind","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/rpcbind?arch=source&distro=esm-infra%2Fxenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.2.1-6ubuntu4","0.2.3-0.2","0.2.3-0.2ubuntu0.1","0.2.3-0.2ubuntu0.16.04.1","0.2.3-0.2ubuntu0.16.04.1+esm1","0.2.3-0.2ubuntu0.16.04.1+esm2","0.2.3-0.2ubuntu0.16.04.1+esm3"],"ecosystem_specific":{"binaries":[{"binary_name":"rpcbind","binary_version":"0.2.3-0.2ubuntu0.16.04.1+esm3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-94640.json"}},{"package":{"name":"rpcbind","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/rpcbind?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.2.3-0.6","0.2.3-0.6ubuntu0.18.04.1","0.2.3-0.6ubuntu0.18.04.2","0.2.3-0.6ubuntu0.18.04.3","0.2.3-0.6ubuntu0.18.04.4"],"ecosystem_specific":{"binaries":[{"binary_name":"rpcbind","binary_version":"0.2.3-0.6ubuntu0.18.04.4"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-94640.json"}},{"package":{"name":"rpcbind","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/rpcbind?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.2.5-6","1.2.5-8"],"ecosystem_specific":{"binaries":[{"binary_name":"rpcbind","binary_version":"1.2.5-8"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-94640.json"}},{"package":{"name":"rpcbind","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/rpcbind?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.2.5-9build1","1.2.6-2","1.2.6-2build1"],"ecosystem_specific":{"binaries":[{"binary_name":"rpcbind","binary_version":"1.2.6-2build1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-94640.json"}},{"package":{"name":"rpcbind","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/rpcbind?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.2.6-6","1.2.6-7","1.2.6-7build1","1.2.6-7ubuntu1","1.2.6-7ubuntu2"],"ecosystem_specific":{"binaries":[{"binary_name":"rpcbind","binary_version":"1.2.6-7ubuntu2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-94640.json"}},{"package":{"name":"rpcbind","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/rpcbind?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.2.7-1build1","1.2.7-1build2"],"ecosystem_specific":{"binaries":[{"binary_name":"rpcbind","binary_version":"1.2.7-1build2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-94640.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"type":"Ubuntu","score":"medium"}]}
