The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-003027 advisory.

    The atyfb_ioctl function in drivers/video/fbdev/aty/atyfb_base.c in the Linux kernel through 4.12.10 does     not initialize a certain data structure, which allows local users to obtain sensitive information from     kernel stack memory by reading locations associated with padding bytes.

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 installation on the remote host is affected by the following vulnerabilities :

  - A flaw was found in the Linux kernel where the coredump     implementation does not use locking or other mechanisms     to prevent vma layout or vma flags changes while it     runs. This allows local users to obtain sensitive     information, cause a denial of service (DoS), or     possibly have unspecified other impact by triggering a     race condition with mmget_not_zero or get_task_mm     calls.(CVE-2019-11599)

  - The Siemens R3964 line discipline driver in     drivers/tty/n_r3964.c in the Linux kernel before 5.0.8     has multiple race conditions.(CVE-2019-11486)

  - A race condition in perf_event_open() allows local     attackers to leak sensitive data from setuid programs.
    As no relevant locks (in particular the     cred_guard_mutex) are held during the     ptrace_may_access() call, it is possible for the     specified target task to perform an execve() syscall     with setuid execution before perf_event_alloc()     actually attaches to it, allowing an attacker to bypass     the ptrace_may_access() check and the     perf_event_exit_task(current) call that is performed in     install_exec_creds() during privileged execve()     calls.(CVE-2019-3901)

  - The atyfb_ioctl function in     drivers/video/fbdev/aty/atyfb_base.c in the Linux     kernel through 4.12.10 does not initialize a certain     data structure, which allows local users to obtain     sensitive information from kernel stack memory by     reading locations associated with padding     bytes.(CVE-2017-14156)

  - A flaw was found in the Linux kernel's ext4 filesystem     code. A use-after-free is possible in     ext4_ext_remove_space() function when mounting and     operating a crafted ext4 image.(CVE-2018-10876)

  - A flaw was found in the implementation of the 'fill     buffer', a mechanism used by modern CPUs when a     cache-miss is made on L1 CPU cache. If an attacker can     generate a load operation that would create a page     fault, the execution will continue speculatively with     incorrect data from the fill buffer while the data is     fetched from higher level caches. This response time     can be measured to infer data in the fill buffer.
    (CVE-2018-12130)

  - Modern Intel microprocessors implement hardware-level     micro-optimizations to improve the performance of     writing data back to CPU caches. The write operation is     split into STA (STore Address) and STD (STore Data)     sub-operations. These sub-operations allow the     processor to hand-off address generation logic into     these sub-operations for optimized writes. Both of     these sub-operations write to a shared distributed     processor structure called the 'processor store     buffer'. As a result, an unprivileged attacker could     use this flaw to read private data resident within the     CPU's processor store buffer. (CVE-2018-12126)

  - Microprocessors use a aEUR~load portaEURtm subcomponent to     perform load operations from memory or IO. During a     load operation, the load port receives data from the     memory or IO subsystem and then provides the data to     the CPU registers and operations in the CPUaEURtms     pipelines. Stale load operations results are stored in     the 'load port' table until overwritten by newer     operations. Certain load-port operations triggered by     an attacker can be used to reveal data about previous     stale requests leaking data back to the attacker via a     timing side-channel. (CVE-2018-12127)

  - Uncacheable memory on some microprocessors utilizing     speculative execution may allow an authenticated user     to potentially enable information disclosure via a side     channel with local access. (CVE-2019-11091)

A buggy or     malicious guest may trigger this bug in dom0 or a PV     driver domain, causing a denial of service or     potentially execution of arbitrary code.

  This issue can be mitigated by disabling merges on the underlying   back-end block devices, e.g.:echo 2 >   /sys/block/nvme0n1/queue/nomerges

  - CVE-2017-12146 (stretch only)     Adrian Salido of Google reported a race condition in     access to the'driver_override' attribute for platform     devices in sysfs. If unprivileged users are permitted to     access this attribute, this might allow them to gain     privileges.

A local user with access to an XFS     filesystem that does not have a realtime device can use     this for denial of service.

  - CVE-2017-14489     ChunYu Wang of Red Hat discovered that the iSCSI     subsystem does not properly validate the length of a     netlink message, leading to memory corruption.

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 :

  - The pagemap_open function in fs/proc/task_mmu.c in the     Linux kernel before 3.19.3, as used in Android 6.0.1     before 2016-03-01, allows local users to obtain     sensitive physical-address information by reading a     pagemap file, aka Android internal bug     25739721.(CVE-2016-0823i1/4%0

  - drivers/hid/hid-steelseries.c in the Human Interface     Device (HID) subsystem in the Linux kernel through     3.11, when CONFIG_HID_STEELSERIES is enabled, allows     physically proximate attackers to cause a denial of     service (heap-based out-of-bounds write) via a crafted     device.(CVE-2013-2891i1/4%0

  - The overlayfs implementation in the Linux kernel     through 4.5.2 does not properly maintain POSIX ACL     xattr data, which allows local users to gain privileges     by leveraging a group-writable setgid     directory.(CVE-2016-1575i1/4%0

  - Integer overflow in the vc4_get_bcl function in     drivers/gpu/drm/vc4/vc4_gem.c in the VideoCore DRM     driver in the Linux kernel before 4.9.7 allows local     users to cause a denial of service or possibly have     unspecified other impact via a crafted size value in a     VC4_SUBMIT_CL ioctl call.(CVE-2017-5576i1/4%0

  - The KVM subsystem in the Linux kernel through 3.12.5     allows local users to gain privileges or cause a denial     of service (system crash) via a VAPIC synchronization     operation involving a page-end     address.(CVE-2013-6368i1/4%0

  - It was found that the code in net/sctp/socket.c in the     Linux kernel through 4.10.1 does not properly restrict     association peel-off operations during certain wait     states, which allows local users to cause a denial of     service (invalid unlock and double free) via a     multithreaded application. This vulnerability was     introduced by CVE-2017-5986 fix (commit     2dcab5984841).(CVE-2017-6353i1/4%0

  - net/netfilter/nf_conntrack_proto_dccp.c in the Linux     kernel through 3.13.6 uses a DCCP header pointer     incorrectly, which allows remote attackers to cause a     denial of service (system crash) or possibly execute     arbitrary code via a DCCP packet that triggers a call     to the (1) dccp_new, (2) dccp_packet, or (3) dccp_error     function.(CVE-2014-2523i1/4%0

  - Race condition vulnerability was found in     drivers/misc/mic/vop/vop_vringh.c in the MIC VOP driver     in the Linux kernel before 4.6.1. MIC VOP driver does     two successive reads from user space to read a variable     length data structure. Local user can obtain sensitive     information from kernel memory or can cause DoS by     corrupting kernel memory if the data structure changes     between the two reads.(CVE-2016-5728i1/4%0

  - An issue was discovered in the btrfs filesystem code in     the Linux kernel. An invalid pointer dereference in     io_ctl_map_page() when mounting and operating a crafted     btrfs image is due to a lack of block group item     validation in check_leaf_item() in     fs/btrfs/tree-checker.c function. This could lead to a     system crash and a denial of service.(CVE-2018-14613i1/4%0

  - A flaw was found in the way the Linux kernel handled GS     segment register base switching when recovering from a     #SS (stack segment) fault on an erroneous return to     user space. A local, unprivileged user could use this     flaw to escalate their privileges on the     system.(CVE-2014-9322i1/4%0

  - The keyring_search_aux function in     security/keys/keyring.c in the Linux kernel allows     local users to cause a denial of service via a     request_key system call for the 'dead' key     type.(CVE-2017-6951i1/4%0

  - A flaw was found in the way the Linux kernel's XFS file     system handled replacing of remote attributes under     certain conditions. A local user with access to XFS     file system mount could potentially use this flaw to     escalate their privileges on the     system.(CVE-2015-0274i1/4%0

  - A memory leak in the kernel_read_file function in     fs/exec.c in the Linux kernel through 4.20.11 allows     attackers to cause a denial of service (memory     consumption) by triggering vfs_read     failures.(CVE-2019-8980i1/4%0

  - A flaw was found in the kernel's implementation of the     Berkeley Packet Filter (BPF). A local attacker could     craft BPF code to crash the system by creating a     situation in which the JIT compiler would fail to     correctly optimize the JIT image on the last pass. This     would lead to the CPU executing instructions that were     not part of the JIT code.(CVE-2015-4700i1/4%0

  - A security flaw was discovered in     nl80211_set_rekey_data() function in the Linux kernel     since v3.1-rc1 through v4.13. This function does not     check whether the required attributes are present in a     netlink request. This request can be issued by a user     with CAP_NET_ADMIN privilege and may result in NULL     dereference and a system crash.(CVE-2017-12153i1/4%0

  - The atyfb_ioctl function in     drivers/video/fbdev/aty/atyfb_base.c in the Linux     kernel through 4.12.10 does not initialize a certain     data structure, which allows local users to obtain     sensitive information from kernel stack memory by     reading locations associated with padding     bytes.(CVE-2017-14156i1/4%0

  - kernel/events/core.c in the performance subsystem in     the Linux kernel before 4.0 mismanages locks during     certain migrations, which allows local users to gain     privileges via a crafted application, aka Android     internal bug 31095224.(CVE-2016-6787i1/4%0

  - The ioresources_init function in kernel/resource.c in     the Linux kernel through 4.7, as used in Android before     2016-08-05 on Nexus 6 and 7 (2013) devices, uses weak     permissions for /proc/iomem, which allows local users     to obtain sensitive information by reading this file,     aka Android internal bug 28814213 and Qualcomm internal     bug CR786116. NOTE: the permissions may be intentional     in most non-Android contexts.(CVE-2015-8944i1/4%0

  - Race condition in the ioctl_file_dedupe_range function     in fs/ioctl.c in the Linux kernel through 4.7 allows     local users to cause a denial of service (heap-based     buffer overflow) or possibly gain privileges by     changing a certain count value, aka a 'double fetch'     vulnerability.(CVE-2016-6516i1/4%0

  - It was found that the timer functionality in the Linux     kernel ALSA subsystem is prone to a race condition     between read and ioctl system call handlers, resulting     in an uninitialized memory disclosure to user space. A     local user could use this flaw to read information     belonging to other users.(CVE-2017-1000380i1/4%0
