In the Linux kernel, the following vulnerability has been resolved:
smb: client: clear ce->tgthint in free_tgts()
When free_tgts() frees all structures in ce->tlist, ce->tgthint
is left pointing to one of the freed cache_dfs_tgt structures.
If ce->tgthint is not reset before it is used later, it results
in a use-after-free.
Set ce->tgthint to NULL in free_tgts() after the elements are
freed to reflect that no elements remain.
