An update that solves 8 vulnerabilities and has 29 fixes is
now available.
Description:
The openSUSE Leap 15.1 kernel was updated to receive various security and
bugfixes.
The following security bugs were fixed:
-
CVE-2019-0154: An unprotected read access to i915 registers has been
fixed that could have been abused to facilitate a local
denial-of-service attack. (bsc#1135966)
-
CVE-2019-0155: A privilege escalation vulnerability has been fixed in
the i915 module that allowed batch buffers from user mode to gain super
user privileges. (bsc#1135967)
-
CVE-2019-16231: drivers/net/fjes/fjes_main.c did not check the
alloc_workqueue return value, leading to a NULL pointer dereference
(bnc#1150466).
-
CVE-2019-18805: There was a net/ipv4/tcp_input.c signed integer overflow
in tcp_ack_update_rtt() when userspace writes a very large integer to
/proc/sys/net/ipv4/tcp_min_rtt_wlen, leading to a denial of service or
possibly unspecified other impact, aka CID-19fad20d15a6 (bnc#1156187).
-
CVE-2019-17055: base_sock_create in drivers/isdn/mISDN/socket.c in the
AF_ISDN network module did not enforce CAP_NET_RAW, which means that
unprivileged users can create a raw socket, aka CID-b91ee4aa2a21
(bnc#1152782).
-
CVE-2019-11135: Aborting an asynchronous TSX operation on Intel CPUs
with Transactional Memory support could be used to facilitate
sidechannel information leaks out of microarchitectural buffers, similar
to the previously described “Microarchitectural Data Sampling” attack.
The Linux kernel was supplemented with the option to disable TSX
operation altogether (requiring CPU Microcode updates on older systems)
and better flushing of microarchitectural buffers (VERW).
The set of options available is described in our TID at
https://www.suse.com/support/kb/doc/?id=7024251
-
CVE-2018-12207: Untrusted virtual machines on Intel CPUs could exploit a
race condition in the Instruction Fetch Unit of the Intel CPU to cause a
Machine Exception during Page Size Change, causing the CPU core to be
non-functional.
The Linux Kernel kvm hypervisor was adjusted to avoid page size changes
in executable pages by splitting / merging huge pages into small pages as
needed.
