{"apiVersion":"1.0","identifier":"CVE-2026-79619","description":"On Linux, several OpenZFS ioctl authorization checks accept a capability held only within a user-created, unprivileged namespace as equivalent to real host privilege, allowing an unprivileged local user to perform operations that should require root. Affected operations include pool-administrative operations (eg create, import, destroy), pool event log access (zpool events) and fault injection (zinject). Exploiting the problem requires only that the local user is permitted to open /dev/zfs (governed by local device permissions) and that the kernel permits unprivileged user namespace creation. No prior access to the target pool or its underlying devices is needed.","publishedAt":"2026-08-26T13:19:24","lastModifiedAt":"2026-08-28T15:24:38","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-79619","cvssScore":7.3,"cvssVector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","epssProbability":0.00139,"riskScore":0.74,"affectedProduct":"OpenZFS","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-79619","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-79619","en":"https://www.redsauce.net/en/cves/CVE-2026-79619","fr":"https://www.redsauce.net/fr/cves/CVE-2026-79619","pt":"https://www.redsauce.net/pt/cves/CVE-2026-79619","de":"https://www.redsauce.net/de/cves/CVE-2026-79619","sk":"https://www.redsauce.net/sk/cves/CVE-2026-79619","el":"https://www.redsauce.net/el/cves/CVE-2026-79619"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-79619"}}
