  • 4.7 (Medium) CVSS_V3 - CVSS:3.0/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N CVSS Calculator
Summary
[none]
Details

An issue was discovered in the Linux kernel before 4.19.3. cryptoreportone() and related functions in crypto/cryptouser.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 CONFIGCRYPTO_USER kconfig option).
