CVE-2022-50007

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

xfrm: fix refcount leak in __xfrm_policy_check()

The issue happens on an error path in __xfrm_policy_check(). When the fetching process of the object pols[1] fails, the function simply returns 0, forgetting to decrement the reference count of pols[0], which is incremented earlier by either xfrm_sk_policy_lookup() or xfrm_policy_lookup(). This may result in memory leaks.

Fix it by decreasing the reference count of pols[0] in that path.
