[PATCH] crypto/ipsec_mb: fix buffer overrun

[PATCH] crypto/ipsec_mb: fix buffer overrun

[Pablo de Lara]

Memory for ZUC cipher/auth key in session had to be expanded to 32 bytes,
instead of 16 bytes, when adding ZUC-256 support.
However, impact is low as this memory is part of a union
with bigger size than 32 bytes.

Fixes: 8c835018de84 ("crypto/ipsec_mb: support ZUC-256 for aesni_mb")
