{"id":"DEBIAN-CVE-2024-42321","details":"In the Linux kernel, the following vulnerability has been resolved:  net: flow_dissector: use DEBUG_NET_WARN_ON_ONCE  The following splat is easy to reproduce upstream as well as in -stable kernels. Florian Westphal provided the following commit:    d1dab4f71d37 (\"net: add and use __skb_get_hash_symmetric_net\")  but this complementary fix has been also suggested by Willem de Bruijn and it can be easily backported to -stable kernel which consists in using DEBUG_NET_WARN_ON_ONCE instead to silence the following splat given __skb_get_hash() is used by the nftables tracing infrastructure to to identify packets in traces.
