In the Linux kernel, the following vulnerability has been resolved:

eventfs: Fix use-after-free in eventfs_remove_rec()

eventfs_remove_rec() recursively removes the child at the current loop

position. After the recursive call returns, list_for_each_entry() advances

by reading list.next from the removed child.

If free_ei() drops the final reference, release_ei() reuses the list/rcu

union to queue an SRCU callback. The child may be freed before that read.

The eventfs_mutex serializes list updates, but it does not keep the removed

child alive or prevent the SRCU callback from running.

Use list_for_each_entry_safe() to save the next sibling before recursively

removing the current child. (NVD)
