Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or have other impacts.

CVE-2014-9888

Russell King found that on ARM systems, memory allocated for DMA buffers was mapped with executable permission. This made it easier to exploit other vulnerabilities in the kernel.

CVE-2014-9895

Dan Carpenter found that the MEDIA_IOC_ENUM_LINKS ioctl on media devices resulted in an information leak.

CVE-2016-6786 / CVE-2016-6787

It was discovered that the performance events subsystem does not properly manage locks during certain migrations, allowing a local attacker to escalate privileges. This can be mitigated by disabling unprivileged use of performance events: sysctl kernel.perf_event_paranoid=3

CVE-2016-8405

Peter Pi of Trend Micro discovered that the frame buffer video subsystem does not properly check bounds while copying color maps to userspace, causing a heap buffer out-of-bounds read, leading to information disclosure.

CVE-2017-5549

It was discovered that the KLSI KL5KUSB105 serial USB device driver could log the contents of uninitialised kernel memory, resulting in an information leak.

CVE-2017-6001

Di Shen discovered a race condition between concurrent calls to the performance events subsystem, allowing a local attacker to escalate privileges. This flaw exists because of an incomplete fix of CVE-2016-6786. This can be mitigated by disabling unprivileged use of performance events: sysctl kernel.perf_event_paranoid=3

CVE-2017-6074

Andrey Konovalov discovered a use-after-free vulnerability in the DCCP networking code, which could result in denial of service or local privilege escalation. On systems that do not already have the dccp module loaded, this can be mitigated by disabling it: echo >> /etc/modprobe.d/disable-dccp.conf install dccp false

For Debian 7 'Wheezy', these problems have been fixed in version 3.2.84-2.

For Debian 8 'Jessie', these problems have been fixed in version 3.16.39-1+deb8u1 or earlier.

  - Insufficient access control in the Intel(R)     PROSet/Wireless WiFi Software driver before version     21.10 may allow an unauthenticated user to potentially     enable denial of service via adjacent     access.(CVE-2019-0136)

  - 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)

  - 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.(CVE-2019-9506)

  - An issue was discovered in net/wireless/nl80211.c in     the Linux kernel through 5.2.17. It does not check the     length of variable elements in a beacon head, leading     to a buffer overflow.(CVE-2019-16746)

  - In the hidp_process_report in bluetooth, there is an     integer overflow. This could lead to an out of bounds     write with no additional execution privileges needed.
    User interaction is not needed for exploitation.
    Product: Android Versions: Android kernel Android ID:
    A-65853588 References: Upstream kernel.(CVE-2018-9363)

  - An issue was discovered in write_tpt_entry in     drivers/infiniband/hw/cxgb4/mem.c in the Linux kernel     through 5.3.2. The cxgb4 driver is directly calling     dma_map_single (a DMA function) from a stack variable.
    This could allow an attacker to trigger a Denial of     Service, exploitable if this driver is used on an     architecture for which this stack/DMA interaction has     security relevance.(CVE-2019-17075)

  - rtl_p2p_noa_ie in     drivers/net/wireless/realtek/rtlwifi/ps.c in the Linux     kernel through 5.3.6 lacks a certain upper-bound check,     leading to a buffer overflow.(CVE-2019-17666)

  - An issue was discovered in drivers/i2c/i2c-core-smbus.c     in the Linux kernel before 4.14.15. There is an out of     bounds write in the function     i2c_smbus_xfer_emulated.(CVE-2017-18551)

  - The rds_ib_xmit function in net/rds/ib_send.c in the     Reliable Datagram Sockets (RDS) protocol implementation     in the Linux kernel 3.7.4 and earlier allows local     users to cause a denial of service (BUG_ON and kernel     panic) by establishing an RDS connection with the     source IP address equal to the IPoIB interface's own IP     address, as demonstrated by rds-ping.(CVE-2012-2372)

  - In the Linux kernel through 5.3.2,     cfg80211_mgd_wext_giwessid in net/wireless/wext-sme.c     does not reject a long SSID IE, leading to a Buffer     Overflow.(CVE-2019-17133)

  - 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)

  - The kernel in Android before 2016-08-05 on Nexus 7     (2013) devices allows attackers to gain privileges via     a crafted application, aka internal bug     28522518.(CVE-2016-3857)

  - arch/arm64/kernel/sys.c in the Linux kernel before 4.0     allows local users to bypass the 'strict page     permissions' protection mechanism and modify the     system-call table, and consequently gain privileges, by     leveraging write access.(CVE-2015-8967)

  - arch/arm64/kernel/perf_event.c in the Linux kernel     before 4.1 on arm64 platforms allows local users to     gain privileges or cause a denial of service (invalid     pointer dereference) via vectors involving events that     are mishandled during a span of multiple HW     PMUs.(CVE-2015-8955)

  - The __clear_user function in     arch/arm64/lib/clear_user.S in the Linux kernel before     3.17.4 on the ARM64 platform allows local users to     cause a denial of service (system crash) by reading one     byte beyond a /dev/zero page boundary.(CVE-2014-7843)

  - The x86/fpu (Floating Point Unit) subsystem in the     Linux kernel before 4.13.5, when a processor supports     the xsave feature but not the xsaves feature, does not     correctly handle attempts to set reserved bits in the     xstate header via the ptrace() or rt_sigreturn() system     call, allowing local users to read the FPU registers of     other processes on the system, related to     arch/x86/kernel/fpu/regset.c and     arch/x86/kernel/fpu/signal.c.(CVE-2017-15537)
