The Linux kernel for openSUSE Leap 42.1 was updated to the 4.1.15 stable
release, and also includes security and bugfixes.

Following security bugs were fixed:
- CVE-2016-0728: A reference leak in keyring handling with
join_session_keyring() could lead to local attackers gain root
privileges. (bsc#962075).
- CVE-2015-7550: A local user could have triggered a race between read and
revoke in keyctl (bnc#958951).
- CVE-2015-8767: A case can occur when sctp_accept() is called by the
user during a heartbeat timeout event after the 4-way handshake. Since
sctp_assoc_migrate() changes both assoc->base.sk and assoc->ep, the
bh_sock_lock in sctp_generate_heartbeat_event() will be taken with the
listening socket but released with the new association socket. The result
is a deadlock on any future attempts to take the listening socket lock. (bsc#961509)
- CVE-2015-8539: A negatively instantiated user key could have been used
by a local user to leverage privileges (bnc#958463).
- CVE-2015-8569: The (1) pptp_bind and (2) pptp_connect functions in
drivers/net/ppp/pptp.c in the Linux kernel did not verify an address
length, which allowed local users to obtain sensitive information from
kernel memory and bypass the KASLR protection mechanism via a crafted
application (bnc#959190).
- CVE-2015-8543: The networking implementation in the Linux kernel
did not validate protocol identifiers for certain protocol families,
which allowed local users to cause a denial of service (NULL function
pointer dereference and system crash) or possibly gain privileges by
leveraging CLONE_NEWUSER support to execute a crafted SOCK_RAW application
(bnc#958886).
- CVE-2015-8575: Validate socket address length in sco_sock_bind() to
prevent information leak (bsc#959399).
- CVE-2015-8551, CVE-2015-8552: xen/pciback: For
XEN_PCI_OP_disable_msi[|x] only disable if device has MSI(X) enabled
(bsc#957990).
- CVE-2015-8550: Compiler optimizations in the XEN PV backend drivers
could have lead to double fetch vulnerabilities, causing denial of
service or arbitrary code execution (depending on the configuration)
(bsc#957988).
