  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nconfigfs_lookup(): don't leave -\u003es_dentry dangling on failure\n\nNormally -\u003es_dentry is cleared when dentry it's pointing to becomes\nnegative (on eviction, realistically).  However, that only happens\nif dentry gets to be positive in the first place; in case of inode\nallocation failure dentry never becomes positive, so -\u003ed_iput()\nis not called at all.\n\nWe do part of what normally would've been done by configfs_d_iput()\n(dropping the reference to configfs_dirent) manually, but we do\nnot clear -\u003es_dentry there.  Sloppy as it is, it does not matter in\ncase of configfs_create_{dir,link}() - there configfs_dirent does\nnot survive dropping the sole reference to it.\n\nHowever, for configfs_lookup() it *does* survive, with a dangling\npointer to soon to be freed dentry sitting it its -\u003es_dentry.\n\nSubsequent getdents(2) in that directory will end up dereferencing\nthat pointer in order to pick the inode number.  Use after free...\n\nThis is the minimal fix; the right approach is to set the linkage\nbetween dentry and configfs_dirent only after we know that we have\nan inode, but that takes more surgery and the bug had been there\nsince 2006, so...",
