The SUSE Linux Enterprise 11 SP4 kernel was updated to receive various security and bugfixes.
Following security bugs were fixed:
- CVE-2015-7509: Mounting ext4 filesystems in no-journal mode could hav lead to a system crash (bsc#956709).
- CVE-2015-7799: The slhc_init function in drivers/net/slip/slhc.c in the Linux kernel did not ensure that certain slot numbers are valid, which allowed local users to cause a denial of service (NULL pointer dereference and system crash) via a crafted PPPIOCSMAXCID ioctl call (bnc#949936).
- CVE-2015-8104: The KVM subsystem in the Linux kernel allowed guest OS users to cause a denial of service (host OS panic or hang) by triggering many #DB (aka Debug) exceptions, related to svm.c (bnc#954404).
- CVE-2015-5307: The KVM subsystem in the Linux kernel allowed guest OS users to cause a denial of service (host OS panic or hang) by triggering many #AC (aka Alignment Check) exceptions, related to svm.c and vmx.c (bnc#953527).

- CVE-2015-6937: The __rds_conn_create function in net/rds/connection.c in the Linux kernel allowed local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by using a socket that was not properly bound (bnc#945825).
