{"apiVersion":"1.0","identifier":"CVE-2026-72188","description":"In the Linux kernel, the following vulnerability has been resolved: ntfs: sanitize MFT references returned from ntfs_lookup_inode_by_name() ntfs_lookup_inode_by_name() returns MFT references read from directory index entries on disk. These values are untrusted, but the function can currently return an error-marked MFT reference to its callers without validating it. Callers later decode lookup failures with MREF_ERR(). A crafted NTFS image can set the MREF error bit while leaving the low bits as an arbitrary value, causing callers to consume a bogus pseudo-errno instead of treating the lookup result as corrupted on-disk metadata. Fix this at the source by normalizing every error-marked MFT reference returned from ntfs_lookup_inode_by_name() to ERR_MREF(-EIO). Apply this to all four directory lookup return paths so every caller gets a validated result without needing additional checks or an API change. This keeps the sanitization in the common lookup helper, which is cleaner than duplicating validation in each caller.","publishedAt":"2026-08-15T06:21:37","lastModifiedAt":"2026-08-17T06:18:19","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-72188","cvssScore":9.1,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H","epssProbability":0.00467,"riskScore":0.95,"affectedProduct":"linux","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-72188","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-72188","en":"https://www.redsauce.net/en/cves/CVE-2026-72188","fr":"https://www.redsauce.net/fr/cves/CVE-2026-72188","pt":"https://www.redsauce.net/pt/cves/CVE-2026-72188","de":"https://www.redsauce.net/de/cves/CVE-2026-72188","sk":"https://www.redsauce.net/sk/cves/CVE-2026-72188","el":"https://www.redsauce.net/el/cves/CVE-2026-72188"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-72188"}}
