{"apiVersion":"1.0","identifier":"CVE-2026-74287","description":"In the Linux kernel, the following vulnerability has been resolved: sctp: validate embedded address parameter length sctp_verify_asconf() and sctp_verify_param() only validate ADD_IP, DEL_IP, and SET_PRIMARY parameters against a fixed minimum size of sizeof(struct sctp_addip_param) + sizeof(struct sctp_paramhdr). This ensures the outer parameter is large enough to contain an embedded address parameter header, but does not verify that the embedded address parameter-s declared length fits within the bounds of the outer parameter. Later, sctp_process_param() and sctp_process_asconf_param() extract the embedded address parameter and pass it to af->from_addr_param(), which uses the address parameter length to parse the variable-length address payload. A malformed peer can therefore advertise an embedded address parameter length that exceeds the remaining bytes in the enclosing parameter. Validate that addr_param->p.length does not exceed the space available after the sctp_addip_param header before processing the embedded address parameter. Reject malformed parameters when the embedded address length extends beyond the enclosing parameter bounds. This prevents out-of-bounds reads when parsing malformed parameters carried in INIT or ASCONF processing paths.","publishedAt":"2026-08-15T06:22:28","lastModifiedAt":"2026-08-17T06:19:22","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-74287","cvssScore":9.1,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H","epssProbability":0.00514,"riskScore":0.95,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-74287","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-74287","en":"https://www.redsauce.net/en/cves/CVE-2026-74287","fr":"https://www.redsauce.net/fr/cves/CVE-2026-74287","pt":"https://www.redsauce.net/pt/cves/CVE-2026-74287","de":"https://www.redsauce.net/de/cves/CVE-2026-74287","sk":"https://www.redsauce.net/sk/cves/CVE-2026-74287","el":"https://www.redsauce.net/el/cves/CVE-2026-74287"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-74287"}}
