The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-000809 advisory.

    The arch_pick_mmap_layout function in arch/x86/mm/mmap.c in the Linux kernel through 4.5.2 does not     properly randomize the legacy base address, which makes it easier for local users to defeat the intended     restrictions on the ADDR_NO_RANDOMIZE flag, and bypass the ASLR protection mechanism for a setuid or     setgid program, by disabling stack-consumption resource limits.

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.

The SUSE Linux Enterprise 12 kernel was updated to 3.12.60 to receive various security and bugfixes.

The following security bugs were fixed :

  - CVE-2014-9717: fs/namespace.c in the Linux kernel     processes MNT_DETACH umount2 system called without     verifying that the MNT_LOCKED flag is unset, which     allowed local users to bypass intended access     restrictions and navigate to filesystem locations     beneath a mount by calling umount2 within a user     namespace (bnc#928547).

  - CVE-2016-2143: The fork implementation in the Linux     kernel on s390 platforms mishandled the case of four     page-table levels, which allowed local users to cause a     denial of service (system crash) or possibly have     unspecified other impact via a crafted application,     related to arch/s390/include/asm/mmu_context.h and     arch/s390/include/asm/pgalloc.h. (bnc#970504)

  - CVE-2016-2184: The create_fixed_stream_quirk function in     sound/usb/quirks.c in the snd-usb-audio driver in the     Linux kernel allowed physically proximate attackers to     cause a denial of service (NULL pointer dereference or     double free, and system crash) via a crafted endpoints     value in a USB device descriptor (bnc#971125).

  - CVE-2016-2847: fs/pipe.c in the Linux kernel did not     limit the amount of unread data in pipes, which allowed     local users to cause a denial of service (memory     consumption) by creating many pipes with non-default     sizes (bnc#970948).

  - CVE-2016-3134: The netfilter subsystem in the Linux     kernel did not validate certain offset fields, which     allowed local users to gain privileges or cause a denial     of service (heap memory corruption) via an     IPT_SO_SET_REPLACE setsockopt call (bnc#971126).

  - CVE-2016-3136: The mct_u232_msr_to_state function in     drivers/usb/serial/mct_u232.c in the Linux kernel     allowed physically proximate attackers to cause a denial     of service (NULL pointer dereference and system crash)     via a crafted USB device without two interrupt-in     endpoint descriptors (bnc#970955).

  - CVE-2016-3156: The IPv4 implementation in the Linux     kernel mishandled destruction of device objects, which     allowed guest OS users to cause a denial of service     (host OS networking outage) by arranging for a large     number of IP addresses (bnc#971360).

  - CVE-2016-3672: The arch_pick_mmap_layout function in     arch/x86/mm/mmap.c in the Linux kernel did not properly     randomize the legacy base address, which made it easier     for local users to defeat the intended restrictions on     the ADDR_NO_RANDOMIZE flag, and bypass the ASLR     protection mechanism for a setuid or setgid program, by     disabling stack-consumption resource limits     (bnc#974308).

  - CVE-2016-3689: The ims_pcu_parse_cdc_data function in     drivers/input/misc/ims-pcu.c in the Linux kernel allowed     physically proximate attackers to cause a denial of     service (system crash) via a USB device without both a     master and a slave interface (bnc#971628).

  - CVE-2016-4482: The proc_connectinfo function in     drivers/usb/core/devio.c in the Linux kernel did not     initialize a certain data structure, which allowed local     users to obtain sensitive information from kernel stack     memory via a crafted USBDEVFS_CONNECTINFO ioctl call     (bnc#978401).

  - CVE-2016-4486: The rtnl_fill_link_ifmap function in     net/core/rtnetlink.c in the Linux kernel did not     initialize a certain data structure, which allowed local     users to obtain sensitive information from kernel stack     memory by reading a Netlink message (bnc#978822).

  - CVE-2016-4565: The InfiniBand (aka IB) stack in the     Linux kernel incorrectly relied on the write system     call, which allowed local users to cause a denial of     service (kernel memory write operation) or possibly have     unspecified other impact via a uAPI interface     (bnc#979548).

  - CVE-2016-4569: The snd_timer_user_params function in     sound/core/timer.c in the Linux kernel did not     initialize a certain data structure, which allowed local     users to obtain sensitive information from kernel stack     memory via crafted use of the ALSA timer interface     (bnc#979213).
