  - ** DISPUTED ** An issue was discovered in the MPT3COMMAND case in _ctl_ioctl_main in     drivers/scsi/mpt3sas/mpt3sas_ctl.c in the Linux kernel through 5.1.5. It allows local users to cause a     denial of service or possibly have unspecified other impact by changing the value of ioc_number between     two kernel reads of that value, aka a double fetch vulnerability. NOTE: a third party reports that this     is unexploitable because the doubly fetched value is not used. (CVE-2019-12456)

  - A heap-based buffer overflow vulnerability was found in the Linux kernel, version kernel-2.6.32, in     Marvell WiFi chip driver. A remote attacker could cause a denial of service (system crash) or, possibly     execute arbitrary code, when the lbs_ibss_join_existing function is called after a STA connects to an AP.
    (CVE-2019-14896)

  - A stack-based buffer overflow was found in the Linux kernel, version kernel-2.6.32, in Marvell WiFi chip     driver. An attacker is able to cause a denial of service (system crash) or, possibly execute arbitrary     code, when a STA works in IBSS mode (allows connecting stations together without the use of an AP) and     connects to another STA. (CVE-2019-14897)

  - An issue was discovered in the Linux kernel before 5.2.3. There is a use-after-free caused by a malicious     USB device in the drivers/media/usb/dvb-usb/dvb-usb-init.c driver. (CVE-2019-15213)

  - An issue was discovered in the Linux kernel before 5.0.1. There is a memory leak in     register_queue_kobjects() in net/core/net-sysfs.c, which will cause denial of service. (CVE-2019-15916)

  - The Linux kernel before 5.4.1 on powerpc allows Information Exposure because the Spectre-RSB mitigation is     not in place for all applicable CPUs, aka CID-39e72bf96f58. This is related to     arch/powerpc/kernel/entry_64.S and arch/powerpc/kernel/security.c. (CVE-2019-18660)

  - The Linux kernel through 5.3.13 has a start_offset+size Integer Overflow in cpia2_remap_buffer in     drivers/media/usb/cpia2/cpia2_core.c because cpia2 has its own mmap implementation. This allows local     users (with /dev/video0 access) to obtain read and write permissions on kernel physical pages, which can     possibly result in a privilege escalation. (CVE-2019-18675)

  - A memory leak in the bfad_im_get_stats() function in drivers/scsi/bfa/bfad_attr.c in the Linux kernel     through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering     bfa_port_get_stats() failures, aka CID-0e62395da2bd. (CVE-2019-19066)

  - Memory leaks in drivers/net/wireless/ath/ath9k/htc_hst.c in the Linux kernel through 5.3.11 allow     attackers to cause a denial of service (memory consumption) by triggering wait_for_completion_timeout()     failures. This affects the htc_config_pipe_credits() function, the htc_setup_complete() function, and the     htc_connect_service() function, aka CID-853acf7caf10. (CVE-2019-19073)

  - A memory leak in the ath9k_wmi_cmd() function in drivers/net/wireless/ath/ath9k/wmi.c in the Linux kernel     through 5.3.11 allows attackers to cause a denial of service (memory consumption), aka CID-728c1e2a05e4.
    (CVE-2019-19074)

  - In the AppleTalk subsystem in the Linux kernel before 5.1, there is a potential NULL pointer dereference     because register_snap_client may return NULL. This will lead to denial of service in net/appletalk/aarp.c     and net/appletalk/ddp.c, as demonstrated by unregister_snap_client, aka CID-9804501fa122. (CVE-2019-19227)

  - In the Linux kernel before 5.3.7, there is a use-after-free bug that can be caused by a malicious USB     device in the drivers/usb/misc/adutux.c driver, aka CID-44efc269db79. (CVE-2019-19523)

  - In the Linux kernel before 5.3.12, there is a use-after-free bug that can be caused by a malicious USB     device in the drivers/input/ff-memless.c driver, aka CID-fa3a5a1880c9. (CVE-2019-19524)

  - In the Linux kernel before 5.2.10, there is a use-after-free bug that can be caused by a malicious USB     device in the drivers/hid/usbhid/hiddev.c driver, aka CID-9c09b214f30e. (CVE-2019-19527)

  - In the Linux kernel before 5.2.10, there is a use-after-free bug that can be caused by a malicious USB     device in the drivers/usb/class/cdc-acm.c driver, aka CID-c52873e5a1ef. (CVE-2019-19530)

  - In the Linux kernel before 5.2.9, there is a use-after-free bug that can be caused by a malicious USB     device in the drivers/usb/misc/yurex.c driver, aka CID-fc05481b2fca. (CVE-2019-19531)

  - In the Linux kernel before 5.3.9, there are multiple out-of-bounds write bugs that can be caused by a     malicious USB device in the Linux kernel HID drivers, aka CID-d9d4b1e46d95. This affects drivers/hid/hid-     axff.c, drivers/hid/hid-dr.c, drivers/hid/hid-emsff.c, drivers/hid/hid-gaff.c, drivers/hid/hid-holtekff.c,     drivers/hid/hid-lg2ff.c, drivers/hid/hid-lg3ff.c, drivers/hid/hid-lg4ff.c, drivers/hid/hid-lgff.c,     drivers/hid/hid-logitech-hidpp.c, drivers/hid/hid-microsoft.c, drivers/hid/hid-sony.c, drivers/hid/hid-     tmff.c, and drivers/hid/hid-zpff.c. (CVE-2019-19532)

  - In the Linux kernel before 5.2.10, there is a race condition bug that can be caused by a malicious USB     device in the USB character device driver layer, aka CID-303911cfc5b9. This affects     drivers/usb/core/file.c. (CVE-2019-19537)

  - In the Linux kernel 5.4.0-rc2, there is a use-after-free (read) in the __blk_add_trace function in     kernel/trace/blktrace.c (which is used to fill out a blk_io_trace structure and place it in a per-cpu sub-     buffer). (CVE-2019-19768)

  - In the Linux kernel through 5.4.6, there is a NULL pointer dereference in     drivers/scsi/libsas/sas_discover.c because of mishandling of port disconnection during discovery, related     to a PHY down race condition, aka CID-f70267f379b5. (CVE-2019-19965)

  - In the Linux kernel before 5.1.6, there is a use-after-free in cpia2_exit() in     drivers/media/usb/cpia2/cpia2_v4l.c that will cause denial of service, aka CID-dea37a972655.
    (CVE-2019-19966)

  - In the Linux kernel before 5.1, there is a memory leak in __feat_register_sp() in net/dccp/feat.c, which     may cause denial of service, aka CID-1d3ff0950e2b. (CVE-2019-20096)

  - In the Linux kernel before 5.5.8, get_raw_socket in drivers/vhost/net.c lacks validation of an sk_family     field, which might allow attackers to trigger kernel stack corruption via crafted system calls.
    (CVE-2020-10942)

  - An issue was discovered in the Linux kernel before 5.6.1. drivers/media/usb/gspca/ov519.c allows NULL     pointer dereferences in ov511_mode_init_regs and ov518_mode_init_regs when there are zero endpoints, aka     CID-998912346c0d. (CVE-2020-11608)

  - There is a use-after-free vulnerability in the Linux kernel through 5.5.2 in the vc_do_resize function in     drivers/tty/vt/vt.c. (CVE-2020-8647)

  - There is a use-after-free vulnerability in the Linux kernel through 5.5.2 in the n_tty_receive_buf_common     function in drivers/tty/n_tty.c. (CVE-2020-8648)

  - There is a use-after-free vulnerability in the Linux kernel through 5.5.2 in the vgacon_invert_region     function in drivers/video/console/vgacon.c. (CVE-2020-8649)

  - An issue was discovered in the Linux kernel 3.16 through 5.5.6. set_fdc in drivers/block/floppy.c leads to     a wait_til_ready out-of-bounds read because the FDC index is not checked for errors before assigning it,     aka CID-2e90ca68b0d2. (CVE-2020-9383)
