This update for the SUSE Linux Enterprise Server 11 SP3 Kernel for Teradata fixes the following issues:
Security issues fixed:
- CVE-2019-11478: The TCP retransmission queue implementation in tcp_fragment in the Linux kernel could be fragmented when handling certain TCP Selective Acknowledgment (SACK) sequences. A remote attacker could use this to cause a denial of service (bsc#1137586)
- CVE-2019-1125: Exclude ATOMs from speculation through SWAPGS (bsc#1139358)
- CVE-2019-3846: A flaw that allowed an attacker to corrupt memory and possibly escalate privileges was found in the mwifiex kernel module while connecting to a malicious wireless network (bsc#1136424)
- CVE-2019-3459, CVE-2019-3460: A heap address information leak while using L2CAP_GET_CONF_OPT was discovered in the Linux kernel before 5.1-rc1 (bsc#1120758)
- CVE-2019-3896: A double-free can happen in idr_remove_all() in lib/idr.c in the Linux kernel 2.6 branch. An unprivileged local attacker can use this flaw for a privilege escalation or for a system crash and a denial of service (DoS) (bsc#1138943)
- CVE-2018-20836: An issue was discovered in the Linux kernel before 4.20. There is a race condition in smp_task_timedout() and smp_task_done() in drivers/scsi/libsas/sas_expander.c, leading to a use-after-free (bsc#1134395)
- CVE-2019-12614: An issue was discovered in dlpar_parse_cc_property in arch/powerpc/platforms/pseries/dlpar.c in the Linux kernel through 5.1.6. There is an unchecked kstrdup of prop->name, which might allow an attacker to cause a denial of service (NULL pointer dereference and system crash) (bsc#1137194)
Regular bugs fixed:
- Fixed an issue where the error message 'Hyper-V eth0: unable to send receive completion pkt' was shown (bsc#1136795)
