  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\neventfs: Fix use-after-free in eventfs_remove_rec()\n\neventfs_remove_rec() recursively removes the child at the current loop\nposition. After the recursive call returns, list_for_each_entry() advances\nby reading list.next from the removed child.\n\nIf free_ei() drops the final reference, release_ei() reuses the list/rcu\nunion to queue an SRCU callback. The child may be freed before that read.\nThe eventfs_mutex serializes list updates, but it does not keep the removed\nchild alive or prevent the SRCU callback from running.\n\nUse list_for_each_entry_safe() to save the next sibling before recursively\nremoving the current child.",
