[PATCH 0/1][SRU][B] CVE-2018-19854 - Crypto API info leak

 An issue was discovered in the Linux kernel before 4.19.3.
 crypto_report_one() and related functions in crypto/crypto_user.c (the
 crypto user configuration API) do not fully initialize structures that are
 copied to userspace, potentially leaking sensitive memory to user programs.
 NOTE: this is a CVE-2013-2547 regression but with easier exploitability
 because the attacker does not need a capability (however, the system must
 have the CONFIG_CRYPTO_USER kconfig option).

After adjusting the target filename of the patch, this was a clean cherry-pick
to Bionic. I've only boot tested this change in the Bionic kernel.
