  "details": "In the Linux kernel, the following vulnerability has been resolved:  smb: client: clear ce-\u003etgthint in free_tgts()  When free_tgts() frees all structures in ce-\u003etlist, ce-\u003etgthint is left pointing to one of the freed cache_dfs_tgt structures.  If ce-\u003etgthint is not reset before it is used later, it results in a use-after-free.  Set ce-\u003etgthint to NULL in free_tgts() after the elements are freed to reflect that no elements remain.",
