New kernel packages are available for Slackware 14.2 to fix security issues.

The SUSE Linux Enterprise 12-SP3 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed :

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. More information can be found on https://www.suse.com/support/kb/doc/?id=7023735 CVE-2019-16995: Fix a memory leak in hsr_dev_finalize() if hsr_add_port failed to add a port, which may have caused denial of service (bsc#1152685).

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-2019-16233: drivers/scsi/qla2xxx/qla_os.c did not check the alloc_workqueue return value, leading to a NULL pointer dereference. (bsc#1150457).

CVE-2019-15902: A backporting issue was discovered that re-introduced the Spectre vulnerability it had aimed to eliminate. This occurred because the backport process depends on cherry picking specific commits, and because two (correctly ordered) code lines were swapped (bnc#1149376).

The 9p filesystem did     not protect i_size_write() properly, which causes an     i_size_read() infinite loop and denial of service on     SMP systems.(CVE-2019-16413)An issue was discovered in     xfs_setattr_nonsize in fs/xfs/xfs_iops.c in the Linux     kernel through 5.2.9. XFS partially wedges when a chgrp     fails on account of being out of disk quota.
    xfs_setattr_nonsize is failing to unlock the ILOCK     after the xfs_qm_vop_chown_reserve call fails. This is     primarily a local DoS attack vector, but it might     result as well in remote DoS if the XFS filesystem is     exported for instance via NFS.(CVE-2019-15538)A buffer     overflow flaw was found, in versions from 2.6.34 to     5.2.x, in the way Linux kernel's vhost functionality     that translates virtqueue buffers to IOVs, logged the     buffer descriptors during migration. A privileged guest     user able to pass descriptors with invalid length to     the host when migration is underway, could use this     flaw to increase their privileges on the     host.(CVE-2019-14835)An out-of-bounds access issue was     found in the Linux kernel, all versions through 5.3, in     the way Linux kernel's KVM hypervisor implements the     Coalesced MMIO write operation. It operates on an MMIO     ring buffer 'struct kvm_coalesced_mmio' object, wherein     write indices 'ring->first' and 'ring->last' value     could be supplied by a host user-space process. An     unprivileged host user or process with access to     '/dev/kvm' device could use this flaw to crash the host     kernel, resulting in a denial of service or potentially     escalating privileges on the system.(CVE-2019-14821)An     information disclosure vulnerability exists when     certain central processing units (CPU) speculatively     access memory, aka 'Windows Kernel Information     Disclosure Vulnerability'.
    (CVE-2019-1125)drivers/scsi/qla2xxx/qla_os.c in the     Linux kernel 5.2.14 does not check the alloc_workqueue     return value, leading to a NULL pointer     dereference.(CVE-2019-16233)An issue was discovered in     the Linux kernel before 5.0.11. fm10k_init_module in     drivers et/ethernet/intel/fm10k/fm10k_main.c has a NULL     pointer dereference because there is no -ENOMEM upon an     alloc_workqueue failure.(CVE-2019-15924)An issue was     discovered in the Linux kernel before 5.2.1. There is a     use-after-free caused by a malicious USB device in the     drivers et/wireless/intersil/p54/p54usb.c     driver.(CVE-2019-15220 )In the Linux kernel before     5.1.7, a device can be tracked by an attacker using the     IP ID values the kernel produces for connection-less     protocols (e.g., UDP and ICMP). When such traffic is     sent to multiple destination IP addresses, it is     possible to obtain hash collisions (of indices to the     counter array) and thereby obtain the hashing key (via     enumeration). An attack may be conducted by hosting a     crafted web page that uses WebRTC or gQUIC to force UDP     traffic to attacker-controlled IP     addresses.(CVE-2019-10638)There is heap-based buffer     overflow in Linux kernel, all versions up to, excluding     5.3, in the marvell wifi chip driver in Linux kernel,     that allows local users to cause a denial of     service(system crash) or possibly execute arbitrary     code.( CVE-2019-14814)** RESERVED ** This candidate has     been reserved by an organization or individual that     will use it when announcing a new security problem.
    When the candidate has been publicized, the details for     this candidate will be provided.( CVE-2019-14815)There     is heap-based buffer overflow in kernel, all versions     up to, excluding 5.3, in the marvell wifi chip driver     in Linux kernel, that allows local users to cause a     denial of service(system crash) or possibly execute     arbitrary code.( CVE-2019-14816)A flaw was found in the     way Linux kernel KVM hypervisor emulated instructions     such as sgdt/sidt/fxsave/fxrstor. It did not check     current privilege(CPL) level while emulating     unprivileged instructions. An unprivileged guest     user/process could use this flaw to potentially     escalate privileges inside guest.(CVE-2018-10853)A NULL     pointer dereference was found in the net/rds/rdma.c
    __rds_rdma_map() function in the Linux kernel before     4.14.7 allowing local attackers to cause a system panic     and a denial-of-service, related to RDS_GET_MR and     RDS_GET_MR_FOR_DEST.(CVE-2018-7492)An issue was     discovered in the Linux kernel before 4.20.15. The     nfc_llcp_build_tlv function in net fc/llcp_commands.c     may return NULL. If the caller does not check for this,     it will trigger a NULL pointer dereference. This will     cause denial of service. This affects nfc_llcp_build_gb     in netfc/llcp_core.c.(CVE-2019-12818)An issue was     discovered in the Linux kernel before 5.1.8. There is a     NULL pointer dereference caused by a malicious USB     device in the drivers/media/usb/siano/smsusb.c     driver.(CVE-2019-15218)An issue was discovered in the     Linux kernel before 5.1.8. There is a NULL pointer     dereference caused by a malicious USB device in the     drivers/usb/misc/sisusbvga/sisusb.c     driver.(CVE-2019-15219)An issue was discovered in the     Linux kernel before 5.1.17. There is a NULL pointer     dereference caused by a malicious USB device in the     sound/usb/line6/pcm.c driver.(CVE-2019-15221)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - An issue was discovered in the Linux kernel before 5.2.1. There is a use-after-free caused by a malicious     USB device in the drivers/net/wireless/intersil/p54/p54usb.c driver. (CVE-2019-15220)

Note that Nessus relies on the presence of the package as reported by the vendor.
