{"apiVersion":"1.0","identifier":"CVE-2026-72185","description":"In the Linux kernel, the following vulnerability has been resolved: ntfs: fix WARN_ON for resident attribute in ntfs_map_runlist_nolock() When ntfs_map_runlist_nolock() needs to look up the attribute extent containing a target VCN (ctx_needs_reset == true), it calls ntfs_attr_lookup() and then expects the result to be a non-resident attribute, since only non-resident attributes have a mapping pairs array to decompress. A crafted NTFS image can place a resident attribute where a non-resident one is expected, causing ntfs_attr_lookup() to succeed but return a resident attribute record. Previously this was caught only by a WARN_ON(), which does not stop execution. The code then falls through to read a->data.non_resident.highest_vcn from what is actually a resident attribute, accessing the wrong union member and corrupting the VCN range check. The caller path triggering this warning during mount is: ntfs_map_runlist_nolock ntfs_empty_logfile load_system_files ntfs_fill_super In this path ctx is NULL, so ntfs_map_runlist_nolock() allocates a temporary search context internally and sets ctx_needs_reset = true. The existing resident-attribute guard in the ctx != NULL branch already returns -EIO silently for the same condition; make the ctx_needs_reset path consistent by replacing the WARN_ON() with the same -EIO error return. This causes the crafted image to be rejected with a mount error instead of triggering a kernel warning.","publishedAt":"2026-08-15T06:21:36","lastModifiedAt":"2026-08-17T06:18:19","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-72185","cvssScore":9.8,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.00626,"riskScore":1.04,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-72185","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-72185","en":"https://www.redsauce.net/en/cves/CVE-2026-72185","fr":"https://www.redsauce.net/fr/cves/CVE-2026-72185","pt":"https://www.redsauce.net/pt/cves/CVE-2026-72185","de":"https://www.redsauce.net/de/cves/CVE-2026-72185","sk":"https://www.redsauce.net/sk/cves/CVE-2026-72185","el":"https://www.redsauce.net/el/cves/CVE-2026-72185"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-72185"}}
