When the host is configured with a small interface MTU, a guest-supplied DHCPv6 CLIENTID option or TFTP blksize option can overflow the reply buffer with attacker-controlled content and length, resulting in denial of service and potentially arbitrary code execution in the host process. The default interface MTU is not affected.","epss":{"date":"2026-11-02","percentile":0.47188,"score":0.0057},"exploits":[],"kev":null,"metrics":[{"score":7.4,"severity":"high","source":"CNA: redhat","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:H","version":"3.1"},{"score":7.4,"severity":"high","source":"NVD: secalert@redhat.com","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:H","version":"3.1"}],"modifiedAt":1793683135623,"publishedAt":1790066161598,"references":[{"source":"CNA: redhat","tags":["vdb-entry","x_refsource_REDHAT"],"url":"https://access.redhat.com/security/cve/CVE-2026-95508"},{"source":"CNA: redhat","tags":["issue-tracking","x_refsource_REDHAT"],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2537748"},{"source":"secalert@redhat.com","tags":[],"url":"https://access.redhat.com/security/cve/CVE-2026-95508"},{"source":"secalert@redhat.com","tags":[],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2537748"}],"remediation":[{"kind":"workaround","source":"CNA: redhat","text":"Do not configure SlirpConfig.if_mtu below the IPv6 minimum link MTU of 1280."}],"revision":"1fed86be7839354e4a06b9fbef71b806931d7a2c52704b8e9bff1c0473b5439c","sources":[{"modifiedAt":1793679359974,"name":"CNA: redhat","retrievedAt":1793682660094,"url":"https://www.cve.org/CVERecord?id=CVE-2026-95508"},{"modifiedAt":1793683135623,"name":"NVD","retrievedAt":1793686545644,"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-95508"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1793682660775,"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-95508"}],"ssvc":{"assessedAt":1790093600788,"automatable":"no","exploitation":"none","source":"ADP: CISA-ADP","technicalImpact":"partial"},"status":"published","title":"Libslirp: libslirp: heap buffer overflow in dhcpv6/tftp response builders on small interface mtu","updatedAt":1793686545644}
