Summary
It was discovered that an integer overflow existed in the perf subsystem of
the Linux kernel. A local attacker could use this to cause a denial of
service (system crash). (CVE-2017-18255)
Wei Fang discovered an integer overflow in the F2FS filesystem
implementation in the Linux kernel. A local attacker could use this to
cause a denial of service. (CVE-2017-18257)
It was discovered that an information leak existed in the generic SCSI
driver in the Linux kernel. A local attacker could use this to expose
sensitive information (kernel memory). (CVE-2018-1000204)
It was discovered that the wait4() system call in the Linux kernel did not
properly validate its arguments in some situations. A local attacker could
possibly use this to cause a denial of service. (CVE-2018-10087)
It was discovered that the kill() system call implementation in the Linux
kernel did not properly validate its arguments in some situations. A local
attacker could possibly use this to cause a denial of service.
(CVE-2018-10124)
Julian Stecklina and Thomas Prescher discovered that FPU register states
(such as MMX, SSE, and AVX registers) which are lazily restored are
potentially vulnerable to a side channel attack. A local attacker could use
this to expose sensitive information. (CVE-2018-3665)
Jakub Jirasek discovered that multiple use-after-free errors existed in the
USB/IP implementation in the Linux kernel. A local attacker could use this
to cause a denial of service (system crash) or possibly execute arbitrary
code. (CVE-2018-5814)
It was discovered that an information leak vulnerability existed in the
floppy driver in the Linux kernel. A local attacker could use this to
expose sensitive information (kernel memory). (CVE-2018-7755)
Seunghun Han discovered an information leak in the ACPI handling code in
the Linux kernel when handling early termination of ACPI table loading. A
local attacker could use this to expose sensitive informal (kernel address
locations). (CVE-2017-13695)
It was discovered that a memory leak existed in the Serial Attached SCSI
(SAS) implementation in the Linux kernel. A physically proximate attacker
could use this to cause a denial of service (memory exhaustion).
(CVE-2018-10021)
