The following security bugs were fixed:
CVE-2019-10638: In the Linux kernel, a device could be tracked by an
attacker using the IP ID values the kernel produces for connection-less
protocols (e.g., UDP and ICMP). When such traffic was sent to multiple
destination IP addresses, it was possible to obtain hash collisions (of
indices to the counter array) and thereby obtain the hashing key (via
enumeration). An attack may have been conducted by hosting a crafted web
page that uses WebRTC or gQUIC to force UDP traffic to
attacker-controlled IP addresses (bnc#1140575 1140577).
CVE-2019-10639: The Linux kernel allowed Information Exposure (partial
kernel address disclosure), leading to a KASLR bypass. Specifically, it
was possible to extract the KASLR kernel image offset using the IP ID
values the kernel produces for connection-less protocols (e.g., UDP and
ICMP). When such traffic was sent to multiple destination IP addresses,
it was possible to obtain hash collisions (of indices to the counter
array) and thereby obtain the hashing key (via enumeration). This key
contains enough bits from a kernel address (of a static variable) so
when the key was extracted (via enumeration), the offset of the kernel
image was exposed. This attack could be carried out remotely, by the
attacker forcing the target device to send UDP or ICMP (or certain
other) traffic to attacker-controlled IP addresses. Forcing a server to
send UDP traffic is trivial if the server is a DNS server. ICMP traffic
is trivial if the server answers ICMP Echo requests (ping). For client
targets, if the target visits the attacker's web page, then WebRTC or
gQUIC can be used to force UDP traffic to attacker-controlled IP
addresses. NOTE: this attack against KASLR became viable because IP ID
generation was changed to have a dependency on an address associated
with a network namespace (bnc#1140577).
CVE-2019-13233: In arch/x86/lib/insn-eval.c in the Linux kernel, there
was a use-after-free for access to an LDT entry because of a race
condition between modify_ldt() and a #BR exception for an MPX bounds
violation (bnc#1140454).
CVE-2018-20836: An issue was discovered in the Linux kernel There was a
race condition in smp_task_timedout() and smp_task_done() in
drivers/scsi/libsas/sas_expander.c, leading to a use-after-free
(bnc#1134395).
CVE-2019-10126: A flaw was found in the Linux kernel. A heap based
buffer overflow in mwifiex_uap_parse_tail_ies function in
drivers/net/wireless/marvell/mwifiex/ie.c might have lead to memory
corruption and possibly other consequences (bnc#1136935).
CVE-2019-11599: The coredump implementation in the Linux kernel did not
use locking or other mechanisms to prevent vma layout or vma flags
changes while it ran, which allowed local users to obtain sensitive
