{"apiVersion":"1.0","identifier":"CVE-2026-49430","description":"The ZFS_IOC_RECV_NEW ioctl, in the heal receive path, similarly truncated a 64-bit payload size to a 32-bit integer for allocation, then used the original 64-bit size as the length for a byteswap operation. A local user with the -receive- delegated ZFS permission can trigger kernel memory corruption via ZFS_IOC_RECV_NEW by sending a crafted receive stream in heal mode.","publishedAt":"2026-08-19T06:17:42","lastModifiedAt":"2026-08-26T18:16:37","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-49430","cvssScore":7.8,"cvssVector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.00162,"riskScore":0.79,"affectedProduct":"ZFS","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-49430","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-49430","en":"https://www.redsauce.net/en/cves/CVE-2026-49430","fr":"https://www.redsauce.net/fr/cves/CVE-2026-49430","pt":"https://www.redsauce.net/pt/cves/CVE-2026-49430","de":"https://www.redsauce.net/de/cves/CVE-2026-49430","sk":"https://www.redsauce.net/sk/cves/CVE-2026-49430","el":"https://www.redsauce.net/el/cves/CVE-2026-49430"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-49430"}}
