-Subject: [PATCH] nstat: NULL Dereference when no entries specified
-
-The NULL Pointer Dereference vulnerability happens in load_ugly_table(), misc/nstat.c, in the latest version of iproute2.
-The vulnerability can be triggered by:
-1. db is set to NULL at struct nstat_ent *db = NULL;
-2. n is set to NULL at n = db;
-3. NULL dereference of variable n happens at sscanf(p+1, "%llu", &n->val) != 1
