the Linux kernel did not properly validate elliptic curve parameters during
Diffie-Hellman key exchange in some situations. An attacker could use this
to expose sensitive information. (CVE-2018-5383)

It was discovered that a heap buffer overflow existed in the Marvell
Wireless LAN device driver for the Linux kernel. An attacker could use this
to cause a denial of service (system crash) or possibly execute arbitrary
code. (CVE-2019-10126)

Andrei Vlad Lutas and Dan Lutas discovered that some x86 processors
incorrectly handle SWAPGS instructions during speculative execution. A
local attacker could use this to expose sensitive information (kernel
memory). (CVE-2019-1125)

Jann Horn discovered that a race condition existed in the Linux kernel when
performing core dumps. A local attacker could use this to cause a denial of
service (system crash) or expose sensitive information. (CVE-2019-11599)

It was discovered that the PowerPC dlpar implementation in the Linux kernel
did not properly check for allocation errors in some situations. A local
attacker could possibly use this to cause a denial of service (system
crash). (CVE-2019-12614)

Jann Horn discovered that the ptrace implementation in the Linux kernel did
not properly record credentials in some situations. A local attacker could
use this to cause a denial of service (system crash) or possibly gain
administrative privileges. (CVE-2019-13272)

It was discovered that the Marvell Wireless LAN device driver in the Linux
kernel did not properly validate the BSS descriptor. A local attacker could
possibly use this to cause a denial of service (system crash) or possibly
execute arbitrary code. (CVE-2019-3846)");
