The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-000603 advisory.

    arch/arm/mm/dma-mapping.c in the Linux kernel before 3.13 on ARM platforms, as used in Android before     2016-08-05 on Nexus 5 and 7 (2013) devices, does not prevent executable DMA mappings, which might allow     local users to gain privileges via a crafted application, aka Android internal bug 28803642 and Qualcomm     internal bug CR642735.

Tenable has extracted the preceding description block directly from the Unity Linux security advisory.

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

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.

We recommend that you upgrade your linux packages.

  - In ashmem_ioctl of ashmem.c, there is an out-of-bounds     write due to insufficient locking when accessing asma.
    This could lead to a local elevation of privilege     enabling code execution as a privileged process with no     additional execution privileges needed. User     interaction is not needed for exploitation. Product:
    Android. Versions: Android kernel. Android ID:
    A-66954097.(CVE-2017-13216)

  - A certain backport in the TCP Fast Open implementation     for the Linux kernel before 3.18 does not properly     maintain a count value, which allow local users to     cause a denial of service (system crash) via the Fast     Open feature, as demonstrated by visiting the     chrome://flags/#enable-tcp-fast-open URL when using     certain 3.10.x through 3.16.x kernel builds, including     longterm-maintenance releases and ckt (aka Canonical     Kernel Team) builds.(CVE-2015-3332)

  - The rtnl_fill_link_ifmap function in     net/core/rtnetlink.c in the Linux kernel before 4.5.5     does not initialize a certain data structure, which     allows local users to obtain sensitive information from     kernel stack memory by reading a Netlink     message.(CVE-2016-4486)

  - The ip6gre_err function in net/ipv6/ip6_gre.c in the     Linux kernel allows remote attackers to have     unspecified impact via vectors involving GRE flags in     an IPv6 packet, which trigger an out-of-bounds     access.(CVE-2017-5897)

  - In the Linux kernel before version 4.12, Kerberos 5     tickets decoded when using the RXRPC keys incorrectly     assumes the size of a field. This could lead to the     size-remaining variable wrapping and the data pointer     going over the end of the buffer. This could possibly     lead to memory corruption and possible privilege     escalation.(CVE-2017-7482)

  - A flaw was found in the Linux Kernel where an attacker     may be able to have an uncontrolled read to     kernel-memory from within a vm guest. A race condition     between connect() and close() function may allow an     attacker using the AF_VSOCK protocol to gather a 4 byte     information leak or possibly intercept or corrupt     AF_VSOCK messages destined to other     clients.(CVE-2018-14625)

  - drivers/net/usb/asix_devices.c in the Linux kernel     through 4.13.11 allows local users to cause a denial of     service (NULL pointer dereference and system crash) or     possibly have unspecified other impact via a crafted     USB device.(CVE-2017-16647)

  - A memory leak in the ql_alloc_large_buffers() function     in drivers/net/ethernet/qlogic/qla3xxx.c in the Linux     kernel before 5.3.5 allows local users to cause a     denial of service (memory consumption) by triggering     pci_dma_mapping_error() failures, aka     CID-1acb8f2a7a9f.(CVE-2019-18806)

  - An issue was discovered in the fd_locked_ioctl function     in drivers/block/floppy.c in the Linux kernel through     4.15.7. The floppy driver will copy a kernel pointer to     user memory in response to the FDGETPRM ioctl. An     attacker can send the FDGETPRM ioctl and use the     obtained kernel pointer to discover the location of     kernel code and data and bypass kernel security     protections such as KASLR.(CVE-2018-7755)

  - The usbvision driver in the Linux kernel package     3.10.0-123.20.1.el7 through 3.10.0-229.14.1.el7 in Red     Hat Enterprise Linux (RHEL) 7.1 allows physically     proximate attackers to cause a denial of service     (panic) via a nonzero bInterfaceNumber value in a USB     device descriptor.(CVE-2015-7833)

  - 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)

  - drivers/net/wireless/intel/iwlwifi/pcie/trans.c in the     Linux kernel 5.2.14 does not check the alloc_workqueue     return value, leading to a NULL pointer     dereference.(CVE-2019-16234)

  - drivers/net/fjes/fjes_main.c in the Linux kernel 5.2.14     does not check the alloc_workqueue return value,     leading to a NULL pointer dereference.(CVE-2019-16231)

  - 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)
