An update that solves 6 vulnerabilities and has 21 fixes is now available.
Description:
The SUSE Linux Enterprise 12 SP2 LTSS kernel was updated to receive various
security and bugfixes.
The following security bugs were fixed:
o CVE-2019-2024: A use-after-free when disconnecting a source was fixed which
could lead to crashes. bnc#1129179).
o CVE-2019-9213: expand_downwards in mm/mmap.c lacked a check for the mmap
minimum address, which made it easier for attackers to exploit kernel NULL
pointer dereferences on non-SMAP platforms. This is related to a capability
check for the wrong task (bnc#1128166).
o CVE-2018-14633: A security flaw was found in the chap_server_compute_md5()
function in the ISCSI target code in the Linux kernel in a way an
authentication request from an ISCSI initiator is processed. (bnc#1107829).
o CVE-2019-7221: The KVM implementation in the Linux kernel had a
Use-after-Free (bnc#1124732).
o CVE-2019-7222: The KVM implementation in the Linux kernel had an
Information Leak (bnc#1124735).
o CVE-2019-6974: kvm_ioctl_create_device in virt/kvm/kvm_main.c mishandled
reference counting because of a race condition, which led to a
use-after-free (bnc#1124728).
The following non-security bugs were fixed:
o copy_mount_string: Limit string length to PATH_MAX (bsc#1082943).
o enic: add wq clean up budget (bsc#1075697, bsc#1120691. bsc#1102959).
o ibmvscsi: Fix empty event pool access during host removal (bsc#1119019).
o ipv4: ipv6: Adjust the frag mem limit after truesize has been changed (bsc#
1110286).
o kmps: obsolete older KMPs of the same flavour (bsc#1127155, bsc#1109137).
o netfilter: ipv6: Adjust the frag mem limit after truesize has been changed
(bsc#1110286).
o perf/x86: Add sysfs entry to freeze counters on SMI (bsc#1121805).
o perf/x86/intel: Delay memory deallocation until x86_pmu_dead_cpu() (bsc#
1121805).
o perf/x86/intel: Do not enable freeze-on-smi for PerfMon V1 (bsc#1121805).
o perf/x86/intel: Fix memory corruption (bsc#1121805).
o perf/x86/intel: Generalize dynamic constraint creation (bsc#1121805).
o perf/x86/intel: Implement support for TSX Force Abort (bsc#1121805).
o perf/x86/intel: Make cpuc allocations consistent (bsc#1121805).
o pseries/energy: Use OF accessor function to read ibm,drc-indexes (bsc#
1129080).
o restore cond_resched() in shrink_dcache_parent() (bsc#1098599, bsc#1105402,
bsc#1127758).
o rps: flow_dissector: Fix uninitialized flow_keys used in __skb_get_hash
possibly (bsc#1108145).
o scsi: megaraid_sas: Send SYNCHRONIZE_CACHE for VD to firmware (bsc#
1121698).
o scsi: sym53c8xx: fix NULL pointer dereference panic in sym_int_sir() (bsc#
1125315).
o x86: Add TSX Force Abort CPUID/MSR (bsc#1121805).
o x86: respect memory size limiting via mem= parameter (bsc#1117645).
o x86/spectre_v2: Do not check microcode versions when running under
hypervisors (bsc#1122821).
o x86/xen: dont add memory above max allowed allocation (bsc#1117645).
o xen-netfront: Fix hang on device removal (bnc#1012382).
o xfrm: use complete IPv6 addresses for hash (bsc#1109330).
o xfs: remove filestream item xfs_inode reference (bsc#1127961).
