The crypto_report_one function in crypto/crypto_user.c in the report API in the crypto user configuration API in the Linux kernel through 3.8.2 does not initialize certain structure members, which allows local users to obtain sensitive information from kernel heap memory by leveraging the CAP_NET_ADMIN capability.

CVE-2018-19854 [LOW] CWE-200 GHSA-328v-h46x-hhhx: An issue was discovered in the Linux kernel before 4
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).

Title: Linux kernel vulnerabilities
Summary: Several security issues were fixed in the kernel.
Emese Revfy discovered that in the Linux kernel signal handlers could leak
address information across an exec, making it possible to by pass ASLR
(Address Space Layout Randomization). A local user could use this flaw to
by pass ASLR to reliably deliver an exploit payload that would otherwise be
stopped (by ASLR). (CVE-2013-0914)
A memory use after free error was discover in the Linux kernel's tmpfs
filesystem. A local user could exploit this flaw to gain privileges or
cause a denial of service (system crash). (CVE-2013-1767)
Mateusz Guzik discovered a race in the Linux kernel's keyring. A local user
could exploit this flaw to cause a denial of service (system crash).
