Hi, For tag only AEAD decrypt operation(Zero length Payload). The dst sg list pointer panic with general protection fault. I think it should be NULL when output buffer is supposed to be empty. Kcapi command to re-produce the issue ./kcapi -x 2 -c "gcm(aes)" -i 0d92aa861746b324f20ee6b7 -k f4a6a5e5f2066f6dd9ec6fc5169c29043560ef595c9e81e76f42d29212cc581c -a "" -t "5f24c68cbe6f32c29652442bf5d483ad" -q "" Its decrypt operation. Expected result should be EBADMSG. Regards Harsh Jain
