{"id":"CVE-2026-72189","summary":"ntfs: fail attrlist updates when the superblock is inactive","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nntfs: fail attrlist updates when the superblock is inactive\n\ngeneric_shutdown_super() clears SB_ACTIVE before evicting cached inodes.\nIf eviction selects the fake inode for a base inode's unnamed\n$ATTRIBUTE_LIST attribute, ntfs_evict_big_inode() drops the fake inode's\nreference on the base inode while the fake inode is still hashed and marked\nI_FREEING.\n\nThat iput can synchronously write back the base inode. The writeback path\nmay update mapping pairs and call ntfs_attrlist_update(), which\nunconditionally calls ntfs_attr_iget() for the same $ATTRIBUTE_LIST fake\ninode. VFS then finds the I_FREEING inode and waits for eviction to finish,\nbut the current task is still inside that eviction path, causing a\nself-deadlock in find_inode().\n\nFix this by mirroring the teardown guard used by __ntfs_write_inode():\nonce SB_ACTIVE has been cleared, do not try to iget the attribute-list\nfake inode. Return -EIO so teardown aborts the update instead of waiting on\nthe inode it is evicting.","modified":"2026-08-18T03:31:30.531416401Z","published":"2026-08-15T05:53:50.373Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72189.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0ebe8f625ab0520217a425d7cd366e4670484941"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d5379035355c0dcb1e92a2544d40f48441e1d637"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72189.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72189"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"495e90fa334828d4119061e2726af51d0a0fb4ed"},{"fixed":"d5379035355c0dcb1e92a2544d40f48441e1d637"},{"fixed":"0ebe8f625ab0520217a425d7cd366e4670484941"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72189.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"7.1.0"},{"fixed":"7.1.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72189.json"}}],"schema_version":"1.9.0"}
