Description (CNA)
In the Linux kernel, the following vulnerability has been resolved: SUNRPC: Fix null pointer dereference in svc_rqst_free() When alloc_pages_node() returns null in svc_rqst_alloc(), the null rq_scratch_page pointer will be dereferenced when calling put_page() in svc_rqst_free(). Fix it by adding a null check. Addresses-Coverity: ("Dereference after null check")
