  - An issue was discovered in the Linux kernel before     4.18.7. In block/blk-core.c, there is an
    __blk_drain_queue() use-after-free because a certain     error case is mishandled. (CVE-2018-20856)

  - A flaw was found in the Linux kernel. A heap based     buffer overflow in mwifiex_uap_parse_tail_ies function     in drivers/net/wireless/marvell/mwifiex/ie.c might lead     to memory corruption and possibly other consequences.
    (CVE-2019-10126)

  - A vulnerability was found in Linux kernel's, versions up     to 3.10, implementation of overlayfs. An attacker with     local access can create a denial of service situation     via NULL pointer dereference in ovl_posix_acl_create     function in fs/overlayfs/dir.c. This can allow attackers     with ability to create directories on overlayfs to crash     the kernel creating a denial of service (DOS).
    (CVE-2019-10140)

  - Microarchitectural Data Sampling Uncacheable Memory     (MDSUM): Uncacheable memory on some microprocessors     utilizing speculative execution may allow an     authenticated user to potentially enable information     disclosure via a side channel with local access. A list     of impacted products can be found here: https://www.inte     l.com/content/dam/www/public/us/en/documents/corporate-     information/SA00233-microcode-update-     guidance_05132019.pdf (CVE-2019-11091)

  - 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)

  - 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. (CVE-2019-3846)

  - The Bluetooth BR/EDR specification up to and including     version 5.1 permits sufficiently low encryption key     length and does not prevent an attacker from influencing     the key length negotiation. This allows practical brute-     force attacks (aka KNOB) that can decrypt traffic and     inject arbitrary ciphertext without the victim noticing.

A use after free exists, related to     xfs_fs_fill_super failure.(CVE-2018-20976)In the Linux     kernel before 5.1.13, there is a memory leak in     drivers/scsi/libsas/sas_expander.c when SAS expander     discovery fails. This will cause a BUG and denial of     service.(CVE-2019-15807)A vulnerability was found in     Linux kernel's, versions up to 3.10, implementation of     overlayfs. An attacker with local access can create a     denial of service situation via NULL pointer     dereference in ovl_posix_acl_create function in     fs/overlayfs/dir.c. This can allow attackers with     ability to create directories on overlayfs to crash the     kernel creating a denial of service     (DOS).(CVE-2019-10140)In the Linux kernel, a certain     net/ipv4/tcp_output.c change, which was properly     incorporated into 4.16.12, was incorrectly backported     to the earlier longterm kernels, introducing a new     vulnerability that was potentially more severe than the     issue that was intended to be fixed by backporting.
    Specifically, by adding to a write queue between     disconnection and re-connection, a local attacker can     trigger multiple use-after-free conditions. This can     result in a kernel crash, or potentially in privilege     escalation.(CVE-2019-15239)check_input_term in     sound/usb/mixer.c in the Linux kernel through 5.2.9     mishandles recursion, leading to kernel stack     exhaustion.(CVE-2019-15118)drivers     et/wireless/ath/ath10k/usb.c in the Linux kernel     through 5.2.8 has a NULL pointer dereference via an     incomplete address in an endpoint     descriptor.(CVE-2019-15099)drivers     et/wireless/ath/ath6kl/usb.c in the Linux kernel     through 5.2.9 has a NULL pointer dereference via an     incomplete address in an endpoint     descriptor.(CVE-2019-15098)A flaw was found in the     Linux kernel's Bluetooth implementation of UART.

Any     attacker having access to ceph cluster network who is     able to sniff packets on network can use this     vulnerability to authenticate with ceph service and     perform actions allowed by ceph service. Ceph branches     master, mimic, luminous and jewel are believed to be     vulnerable.(CVE-2018-1128)ax25_create in     net/ax25/af_ax25.c in the AF_AX25 network module in the     Linux kernel through 5.3.2 does not enforce     CAP_NET_RAW, which means that unprivileged users can     create a raw socket, aka     CID-0614e2b73768.(CVE-2019-17052)ieee802154_create in     net/ieee802154/socket.c in the AF_IEEE802154 network     module in the Linux kernel through 5.3.2 does not     enforce CAP_NET_RAW, which means that unprivileged     users can create a raw socket, aka     CID-e69dbd4619e7.(CVE-2019-17053)atalk_create in     net/appletalk/ddp.c in the AF_APPLETALK network module     in the Linux kernel through 5.3.2 does not enforce     CAP_NET_RAW, which means that unprivileged users can     create a raw socket, aka     CID-6cc03e8aa36c.(CVE-2019-17054)base_sock_create in     drivers/isdn/mISDN/socket.c in the AF_ISDN network     module in the Linux kernel through 5.3.2 does not     enforce CAP_NET_RAW, which means that unprivileged     users can create a raw socket, aka     CID-b91ee4aa2a21.(CVE-2019-17055)llcp_sock_create in     net fc/llcp_sock.c in the AF_NFC network module in the     Linux kernel through 5.3.2 does not enforce     CAP_NET_RAW, which means that unprivileged users can     create a raw socket, aka     CID-3a359798b176.(CVE-2019-17056)A flaw was found in     the Linux kernel's freescale hypervisor manager     implementation, kernel versions 5.0.x up to, excluding     5.0.17. A parameter passed to an ioctl was incorrectly     validated and used in size calculations for the page     size calculation. An attacker can use this flaw to     crash the system, corrupt memory, or create other     adverse security     affects.(CVE-2019-10142)drivers/media/usb/dvb-usb/techn     isat-usb2.c in the Linux kernel through 5.2.9 has an     out-of-bounds read via crafted USB device traffic     (which may be remote via usbip or     usbredir).(CVE-2019-15505)An issue was discovered in     the Linux kernel before 5.0.4. 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.
