- Modern operating systems implement virtualization of
physical memory to efficiently use available system
resources and provide inter-domain protection through
access control and isolation. The L1TF issue was found
in the way the x86 microprocessor designs have
implemented speculative execution of instructions (a
commonly used performance optimisation) in combination
with handling of page-faults caused by terminated
virtual to physical address resolving process. As a
result, an unprivileged attacker could use this flaw to
read privileged memory of the kernel or other processes
and/or cross guest/host boundaries to read host memory
by conducting targeted cache side-channel attacks.
(CVE-2018-3620, CVE-2018-3646)
- An industry-wide issue was found in the way many modern
microprocessor designs have implemented speculative
execution of instructions past bounds check. The flaw
relies on the presence of a precisely-defined
instruction sequence in the privileged code and the fact
that memory writes occur to an address which depends on
the untrusted value. Such writes cause an update into
the microprocessor's data cache even for speculatively
executed instructions that never actually commit
(retire). As a result, an unprivileged attacker could
use this flaw to influence speculative execution and/or
read privileged memory by conducting targeted cache
side- channel attacks. (CVE-2018-3693)
- A flaw named SegmentSmack was found in the way the Linux
kernel handled specially crafted TCP packets. A remote
attacker could use this flaw to trigger time and
calculation expensive calls to tcp_collapse_ofo_queue()
and tcp_prune_ofo_queue() functions by sending specially
modified packets within ongoing TCP sessions which could
lead to a CPU saturation and hence a denial of service
on the system. Maintaining the denial of service
condition requires continuous two-way TCP sessions to a
reachable open port, thus the attacks cannot be
performed using spoofed IP addresses. (CVE-2018-5390)
- kernel: crypto: privilege escalation in skcipher_recvmsg
function (CVE-2017-13215)
- kernel: mm: use-after-free in do_get_mempolicy function
allows local DoS or other unspecified impact
(CVE-2018-10675)
- kernel: race condition in snd_seq_write() may lead to
UAF or OOB access (CVE-2018-7566)
