The following security issues were fixed:
- CVE-2017-13166: An elevation of privilege vulnerability in the kernel
v4l2 video driver was fixed. (bsc#1085447).
- CVE-2018-8897: A statement in the System Programming Guide of the Intel
64 and IA-32 Architectures Software Developer's Manual (SDM) was
mishandled in the development of some or all operating-system kernels,
resulting in unexpected behavior for #DB exceptions that are deferred by
MOV SS or POP SS, as demonstrated by (for example) privilege escalation
in Windows, macOS, some Xen configurations, or FreeBSD, or a Linux
kernel crash. The MOV to SS and POP SS instructions inhibit interrupts
(including NMIs), data breakpoints, and single step trap exceptions
until the instruction boundary following the next instruction (SDM Vol.
3A, section 6.8.3). (The inhibited data breakpoints are those on memory
accessed by the MOV to SS or POP to SS instruction itself.) Note that
debug exceptions are not inhibited by the interrupt enable (EFLAGS.IF)
system flag (SDM Vol. 3A, section 2.3). If the instruction following the
MOV to SS or POP to SS instruction is an instruction like SYSCALL,
SYSENTER, INT 3, etc. that transfers control to the operating system at
CPL
is complete. OS kernels may not expect this order of events and may
therefore experience unexpected behavior when it occurs (bsc#1090368).
- CVE-2018-8781: The udl_fb_mmap function in drivers/gpu/drm/udl/udl_fb.c
had an integer-overflow vulnerability allowing local users with access
to the udldrmfb driver to obtain full read and write permissions on
kernel physical pages, resulting in a code execution in kernel space
(bsc#1090646).
