Eric Biggers bcae2363e2 libceph: don't WARN() if user tries to add invalid key ... commit b11270853f upstream. The WARN_ON(!key->len) in set_secret() in net/ceph/crypto.c is hit if a user tries to add a key of type "ceph" with an invalid payload as follows (assuming CONFIG_CEPH_LIB=y): echo -e -n '\x01\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00' \ | keyctl padd ceph desc @s This can be hit by fuzzers. As this is merely bad input and not a kernel bug, replace the WARN_ON() with return -EINVAL.
