What the advisory describes

In the Linux kernel, the following vulnerability has been resolved: smb: client: harden DFS cache against invalid target hints Currently, get_tgt_name() returns ERR_PTR(-ENOENT) when ce->tgthint is NULL, and dfs_cache_noreq_update_tgthint() assumes ce->tgthint is always valid. In preparation for clearing ce->tgthint in free_tgts(), harden callers of get_tgt_name() against ERR_PTR results and harden dfs_cache_noreq_update_tgthint() against NULL pointer dereferences.

Source: EUVD (ENISA), in the words of the advisory.
