The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-002571 advisory.

    Off-by-one error in the pipe_advance function in lib/iov_iter.c in the Linux kernel before 4.9.5 allows     local users to obtain sensitive information from uninitialized heap-memory locations in opportunistic     circumstances by reading from a pipe after an incorrect buffer-release decision.

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 :

  - A use-after-free vulnerability was found in DCCP socket     code affecting the Linux kernel since 2.6.16. This     vulnerability could allow an attacker to their escalate     privileges.(CVE-2017-8824i1/4%0

  - The OZWPAN driver in the Linux kernel through 4.0.5     relies on an untrusted length field during packet     parsing, which allows remote attackers to obtain     sensitive information from kernel memory or cause a     denial of service (out-of-bounds read and system crash)     via a crafted packet.(CVE-2015-4004i1/4%0

  - Integer signedness error in the MSM V4L2 video driver     for the Linux kernel 3.x, as used in Qualcomm     Innovation Center (QuIC) Android contributions for MSM     devices and other products, allows attackers to gain     privileges or cause a denial of service (array overflow     and memory corruption) via a crafted application that     triggers an msm_isp_axi_create_stream     call.(CVE-2016-2061i1/4%0

  - A denial of service flaw was found in the way the Linux     kernel's XFS file system implementation ordered     directory hashes under certain conditions. A local     attacker could use this flaw to corrupt the file system     by creating directories with colliding hash values,     potentially resulting in a system     crash.(CVE-2014-7283i1/4%0

  - It was found that the Linux kernel's ping socket     implementation did not properly handle socket unhashing     during spurious disconnects, which could lead to a     use-after-free flaw. On x86-64 architecture systems, a     local user able to create ping sockets could use this     flaw to crash the system. On non-x86-64 architecture     systems, a local user able to create ping sockets could     use this flaw to escalate their privileges on the     system.(CVE-2015-3636i1/4%0

  - Incorrect buffer length handling was found in the     ncp_read_kernel function in fs/ncpfs/ncplib_kernel.c in     the Linux kernel, which could be exploited by malicious     NCPFS servers to crash the kernel or possibly execute     an arbitrary code.(CVE-2018-8822i1/4%0

  - ** DISPUTED ** Kernel Samepage Merging (KSM) in the     Linux kernel 2.6.32 through 4.x does not prevent use of     a write-timing side channel, which allows guest OS     users to defeat the ASLR protection mechanism on other     guest OS instances via a Cross-VM ASL INtrospection     (CAIN) attack. NOTE: the vendor states 'Basically if     you care about this attack vector, disable     deduplication.' Share-until-written approaches for     memory conservation among mutually untrusting tenants     are inherently detectable for information disclosure,     and can be classified as potentially misunderstood     behaviors rather than vulnerabilities.(CVE-2015-2877i1/4%0

  - The tty_set_termios_ldisc() function in     'drivers/tty/tty_ldisc.c' in the Linux kernel before     4.5 allows local users to obtain sensitive information     from kernel memory by reading a tty data     structure.(CVE-2015-8964i1/4%0

  - An issue was discovered in the Linux kernel through     4.17.2. vbg_misc_device_ioctl() in     drivers/virt/vboxguest/vboxguest_linux.c reads the same     user data twice with copy_from_user. The header part of     the user data is double-fetched, and a malicious user     thread can tamper with the critical variables     (hdr.size_in and hdr.size_out) in the header between     the two fetches because of a race condition, leading to     severe kernel errors, such as buffer over-accesses.
    This bug can cause a local denial of service and     information leakage.(CVE-2018-12633i1/4%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-2018-1092i1/4%0

  - fs/f2fs/extent_cache.c in the Linux kernel, before     4.13, mishandles extent trees. This allows local users     to cause a denial of service via an application with     multiple threads.(CVE-2017-18193i1/4%0

  - A design flaw was found in the file extended attribute     handling of the Linux kernel's handling of cached     attributes. Too many entries in the cache cause a soft     lockup while attempting to iterate the cache and access     relevant locks.(CVE-2015-8952i1/4%0

  - Off-by-one error in the pipe_advance function in     lib/iov_iter.c in the Linux kernel before 4.9.5 allows     local users to obtain sensitive information from     uninitialized heap-memory locations in opportunistic     circumstances by reading from a pipe after an incorrect     buffer-release decision.(CVE-2017-5550i1/4%0

  - The HMAC implementation (crypto/hmac.c) in the Linux     kernel, before 4.14.8, does not validate that the     underlying cryptographic hash algorithm is unkeyed.
    This allows a local attacker, able to use the     AF_ALG-based hash interface     (CONFIG_CRYPTO_USER_API_HASH) and the SHA-3 hash     algorithm (CONFIG_CRYPTO_SHA3), to cause a kernel stack     buffer overflow by executing a crafted sequence of     system calls that encounter a missing SHA-3     initialization.(CVE-2017-17806i1/4%0

  - The mp_get_count function in     drivers/staging/sb105x/sb_pci_mp.c in the Linux kernel     before 3.12 does not initialize a certain data     structure, which allows local users to obtain sensitive     information from kernel stack memory via a TIOCGICOUNT     ioctl call.(CVE-2013-4516i1/4%0

  - The perf_cpu_time_max_percent_handler function in     kernel/events/core.c in the Linux kernel before 4.11     allows local users to cause a denial of service     (integer overflow) or possibly have unspecified other     impact via a large value, as demonstrated by an     incorrect sample-rate calculation.(CVE-2017-18255i1/4%0

  - An issue was discovered in the btrfs filesystem code in     the Linux kernel. An invalid pointer dereference in
    __del_reloc_root() in fs/btrfs/relocation.c when     mounting a crafted btrfs image could lead to a system     crash and a denial of service.(CVE-2018-14609i1/4%0

  - The oz_usb_handle_ep_data function in     drivers/staging/ozwpan/ozusbsvc1.c in the OZWPAN driver     in the Linux kernel through 4.0.5 allows remote     attackers to cause a denial of service (divide-by-zero     error and system crash) via a crafted     packet.(CVE-2015-4003i1/4%0

  - drivers/hid/hid-logitech-dj.c in the Human Interface     Device (HID) subsystem in the Linux kernel through     3.11, when CONFIG_HID_LOGITECH_DJ is enabled, allows     physically proximate attackers to cause a denial of     service (NULL pointer dereference and OOPS) or obtain     sensitive information from kernel memory via a crafted     device.(CVE-2013-2895i1/4%0

  - drivers/usb/serial/cypress_m8.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 USB device without both an     interrupt-in and an interrupt-out endpoint descriptor,     related to the cypress_generic_port_probe and     cypress_open functions.(CVE-2016-3137i1/4%0
