CVE-2018-19854
CVE-2018-19854
PUBLISHED
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).
