Note that these bugs were already fixed in upstream and all affected Long Term
Support (LTS) kernels months ago. So this is really only a "surprise" for
people who choose to use known buggy and insecure kernels that don't follow LTS.
Anyway, these sorts of bugs are totally predictable in a complex, new network
filesystem server (ksmbd). Personally I recommend not using ksmbd.
