The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-003100 advisory.

    The arch_timer_reg_read_stable macro in arch/arm64/include/asm/arch_timer.h in the Linux kernel before     4.13 allows local users to cause a denial of service (infinite recursion) by writing to a file under     /sys/kernel/debug in certain circumstances, as demonstrated by a scenario involving debugfs, ftrace,     PREEMPT_TRACER, and FUNCTION_GRAPH_TRACER.

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.

According to the versions of the kernel packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

  - Array index error in the tcm_vhost_make_tpg function in     drivers/vhost/scsi.c in the Linux kernel before 4.0     might allow guest OS users to cause a denial of service     (memory corruption) or possibly have unspecified other     impact via a crafted VHOST_SCSI_SET_ENDPOINT ioctl     call. NOTE: the affected function was renamed to     vhost_scsi_make_tpg before the vulnerability was     announced.(CVE-2015-4036i1/4%0

  - The llc_cmsg_rcv function in net/llc/af_llc.c in the     Linux kernel before 4.5.5 does not initialize a certain     data structure, which allows attackers to obtain     sensitive information from kernel stack memory by     reading a message.(CVE-2016-4485i1/4%0

  - The nr_recvmsg function in net/netrom/af_netrom.c in     the Linux kernel before 3.12.4 updates a certain length     value without ensuring that an associated data     structure has been initialized, which allows local     users to obtain sensitive information from kernel     memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg     system call.(CVE-2013-7269i1/4%0

  - The mct_u232_msr_to_state function in     drivers/usb/serial/mct_u232.c in the Linux kernel     before 4.5.1 allows 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.(CVE-2016-3136i1/4%0

  - An out-of-bounds memory access flaw, CVE-2014-7825, was     found in the syscall tracing functionality of the Linux     kernel's perf subsystem. A local, unprivileged user     could use this flaw to crash the system. Additionally,     an out-of-bounds memory access flaw, CVE-2014-7826, was     found in the syscall tracing functionality of the Linux     kernel's ftrace subsystem. On a system with ftrace     syscall tracing enabled, a local, unprivileged user     could use this flaw to crash the system, or escalate     their privileges.(CVE-2014-7826i1/4%0

  - Linux kernel built with the Kernel-based Virtual     Machine (CONFIG_KVM) support is vulnerable to a null     pointer dereference flaw. It could occur on x86     platform, when emulating an undefined instruction. An     attacker could use this flaw to crash the host kernel     resulting in DoS.(CVE-2016-8630i1/4%0

  - A flaw was found in the Linux kernel's ext4 filesystem.
    A local user can cause an out-of-bound access in     ext4_get_group_info function, a denial of service, and     a system crash by mounting and operating on a crafted     ext4 filesystem image.(CVE-2018-10881i1/4%0

  - The arch_timer_reg_read_stable macro in     arch/arm64/include/asm/arch_timer.h in the Linux kernel     before 4.13 allows local users to cause a denial of     service (infinite recursion) by writing to a file under     /sys/kernel/debug in certain circumstances, as     demonstrated by a scenario involving debugfs, ftrace,     PREEMPT_TRACER, and     FUNCTION_GRAPH_TRACER.(CVE-2017-18261i1/4%0

  - The ip6_route_add function in net/ipv6/route.c in the     Linux kernel through 3.13.6 does not properly count the     addition of routes, which allows remote attackers to     cause a denial of service (memory consumption) via a     flood of ICMPv6 Router Advertisement     packets.(CVE-2014-2309i1/4%0

  - In the Linux kernel before 4.20.2, kernel/sched/fair.c     mishandles leaf cfs_rq's, which allows attackers to     cause a denial of service (infinite loop in     update_blocked_averages) or possibly have unspecified     other impact by inducing a high load.(CVE-2018-20784i1/4%0

  - An issue was discovered in the F2FS filesystem code in     fs/f2fs/inline.c in the Linux kernel. A denial of     service due to the out-of-bounds memory access can     occur for a modified f2fs filesystem     image.(CVE-2018-13099i1/4%0

  - An out-of-bounds write vulnerability was found in the     Linux kernel's vmw_surface_define_ioctl() function, in     the 'drivers/gpu/drm/vmwgfx/vmwgfx_surface.c' file. Due     to the nature of the flaw, privilege escalation cannot     be fully ruled out, although we believe it is     unlikely.(CVE-2017-7294i1/4%0

  - A flaw was found in the way the Linux kernel's KVM     subsystem handled non-canonical addresses when     emulating instructions that change the RIP (for     example, branches or calls). A guest user with access     to an I/O or MMIO region could use this flaw to crash     the guest.(CVE-2014-3647i1/4%0

  - The __munlock_pagevec function in mm/mlock.c in the     Linux kernel, before 4.11.4, allows local users to     cause a denial of service (NR_MLOCK accounting     corruption) via crafted use of mlockall and munlockall     system calls.(CVE-2017-18221i1/4%0

  - ** 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-2018-1120i1/4%0

  - The proc_connectinfo() function in     'drivers/usb/core/devio.c' in the Linux kernel through     4.6 does not initialize a certain data structure, which     allows local users to obtain sensitive information from     kernel stack memory via a crafted USBDEVFS_CONNECTINFO     ioctl call. The stack object 'ci' has a total size of 8     bytes. Its last 3 bytes are padding bytes which are not     initialized and are leaked to     userland.(CVE-2016-4482i1/4%0

  - A vulnerability was found in the Linux kernel. An     unprivileged local user could trigger oops in     shash_async_export() by attempting to force the     in-kernel hashing algorithms into decrypting an empty     data set.(CVE-2016-8646i1/4%0

  - An issue was discovered in the btrfs filesystem code in     the Linux kernel. An invalid NULL pointer dereference     in btrfs_root_node() when mounting a crafted btrfs     image is due to a lack of chunk block group mapping     validation in btrfs_read_block_groups() in the     fs/btrfs/extent-tree.c function and a lack of     empty-tree checks in check_leaf() in     fs/btrfs/tree-checker.c function. This could lead to a     system crash and a denial of service.(CVE-2018-14612i1/4%0

  - It was found that the Linux kernel's TCP/IP protocol     suite implementation for IPv6 allowed the Hop Limit     value to be set to a smaller value than the default     one. An attacker on a local network could use this flaw     to prevent systems on that network from sending or     receiving network packets.(CVE-2015-2922i1/4%0

  - A NULL-pointer dereference flaw was found in the     kernel, which is caused by a race between revoking a     user-type key and reading from it. The issue could be     triggered by an unprivileged user with a local account,     causing the kernel to crash (denial of     service).(CVE-2015-7550i1/4%0
