  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nntfs: fix WARN_ON for resident attribute in ntfs_map_runlist_nolock()\n\nWhen ntfs_map_runlist_nolock() needs to look up the attribute extent\ncontaining a target VCN (ctx_needs_reset == true), it calls\nntfs_attr_lookup() and then expects the result to be a non-resident\nattribute, since only non-resident attributes have a mapping pairs\narray to decompress.\n\nA crafted NTFS image can place a resident attribute where a non-resident\none is expected, causing ntfs_attr_lookup() to succeed but return a\nresident attribute record.  Previously this was caught only by a\nWARN_ON(), which does not stop execution.  The code then falls through to\nread a-\u003edata.non_resident.highest_vcn from what is actually a resident\nattribute, accessing the wrong union member and corrupting the VCN range\ncheck.\n\nThe caller path triggering this warning during mount is:\n\n  ntfs_map_runlist_nolock\n  ntfs_empty_logfile\n  load_system_files\n  ntfs_fill_super\n\nIn this path ctx is NULL, so ntfs_map_runlist_nolock() allocates a\ntemporary search context internally and sets ctx_needs_reset = true.\nThe existing resident-attribute guard in the ctx != NULL branch already\nreturns -EIO silently for the same condition; make the ctx_needs_reset\npath consistent by replacing the WARN_ON() with the same -EIO error\nreturn.\n\nThis causes the crafted image to be rejected with a mount error instead\nof triggering a kernel warning.",
