The race in the original report [1] is the one fixed independently in v6.17 by the rose_neigh refcount conversion: https://git.kernel.org/linus/d860d1faa6b2ce3becfdb8b0c2b048ad31800061 ("net: rose: convert 'use' field to refcount_t", v6.17) https://git.kernel.org/linus/da9c9c877597170b929a6121a68dcd3dd9a80f45 ("net: rose: include node references in rose_neigh refcount", v6.17) The Linux kernel CVE team assigned these commits CVE-2025-39826 and CVE-2025-39827.
