  "description": "In the Linux kernel, the following vulnerability has been resolved:  cachefiles: Fix double unlock in nomem_d_alloc error path  When start_creating() fails and returns -ENOMEM, it has already released the parent directory lock in __start_dirop():      static struct dentry *__start_dirop(...)     {         ...         inode_lock_nested(dir, I_MUTEX_PARENT);         dentry = lookup_one_qstr_excl(name, parent, lookup_flags);         if (IS_ERR(dentry))             inode_unlock(dir);  \u003C-- Lock released on error         return dentry;     }  However, the nomem_d_alloc error path in cachefiles_get_directory() unconditionally calls inode_unlock(d_inode(dir)) again, causing a double unlock that corrupts the rwsem state.  This is a leftover from commit 7ab96df840e60 which replaced manual locking with start_creating() but failed to update the nomem_d_alloc path (while correctly updating mkdir_error and lookup_error paths).",
