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).
