- CVEs with nessus.description==This update for the Linux Kernel 4.4.74-92_38 fixes several issues.
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).
- bsc#1083125: Fixed kgraft: small race in reversion code
- CVE-2018-1087: kernel KVM was vulnerable to a flaw in
the way the Linux kernel's KVM hypervisor handled
exceptions delivered after a stack switch operation via
Mov SS or Pop SS instructions. During the stack switch
operation, the processor did not deliver interrupts and
exceptions, rather they are delivered once the first
instruction after the stack switch is executed. An
unprivileged KVM guest user could use this flaw to crash
the guest or, potentially, escalate their privileges in
the guest (bsc#1090869) before
Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.
