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 :

  - In calc_vm_may_flags of ashmem.c, there is a possible     arbitrary write to shared memory due to a permissions     bypass. This could lead to local escalation of     privilege by corrupting memory shared between     processes, with no additional execution privileges     needed. User interaction is not needed for     exploitation. Product: Android Versions: Android kernel     Android ID: A-142938932(CVE-2020-0009)

  - A flaw was found in the Linux Kernel in versions after     4.5-rc1 in the way mremap handled DAX Huge Pages. This     flaw allows a local attacker with access to a DAX     enabled storage to escalate their privileges on the     system.(CVE-2020-10757)

  - go7007_snd_init in     drivers/media/usb/go7007/snd-go7007.c in the Linux     kernel before 5.6 does not call snd_card_free for a     failure path, which causes a memory leak, aka     CID-9453264ef586.(CVE-2019-20810)

  - In the Android kernel in F2FS driver there is a     possible out of bounds read due to a missing bounds     check. This could lead to local information disclosure     with system execution privileges needed. User     interaction is not needed for     exploitation.(CVE-2019-9445)

  - A flaw was found in the Linux kernels SELinux LSM hook     implementation before version 5.7, where it incorrectly     assumed that an skb would only contain a single netlink     message. The hook would incorrectly only validate the     first netlink message in the skb and allow or deny the     rest of the messages within the skb with the granted     permission without further processing.(CVE-2020-10751)

  - An issue was discovered in the Linux kernel before     5.4.7. The prb_calc_retire_blk_tmo() function in     net/packet/af_packet.c can result in a denial of     service (CPU consumption and soft lockup) in a certain     failure case involving TPACKET_V3, aka     CID-b43d1f9f7067.(CVE-2019-20812)

  - ** DISPUTED ** An issue was discovered in the Linux     kernel through 5.7.1. drivers/tty/vt/keyboard.c has an     integer overflow if k_ascii is called several times in     a row, aka CID-b86dab054059. NOTE: Members in the     community argue that the integer overflow does not lead     to a security issue in this case.(CVE-2020-13974)

  - An issue was discovered in the Linux kernel before     5.0.6. In rx_queue_add_kobject() and     netdev_queue_add_kobject() in net/core/net-sysfs.c, a     reference count is mishandled, aka     CID-a3e23f719f5c.(CVE-2019-20811)

  - A flaw was found in the prctl() function, where it can     be used to enable indirect branch speculation after it     has been disabled. This call incorrectly reports it as     being 'force disabled' when it is not and opens the     system to Spectre v2 attacks. The highest threat from     this vulnerability is to     confidentiality.(CVE-2020-10768)

  - A flaw was found in the Linux kernel's implementation     of the Enhanced IBPB (Indirect Branch Prediction     Barrier). The IBPB mitigation will be disabled when     STIBP is not available or when the Enhanced Indirect     Branch Restricted Speculation (IBRS) is available. This     flaw allows a local attacker to perform a Spectre V2     style attack when this configuration is active. The     highest threat from this vulnerability is to     confidentiality.(CVE-2020-10767)

  - A logic bug flaw was found in the Linux kernel's     implementation of SSBD. A bug in the logic handling     allows an attacker with a local account to disable SSBD     protection during a context switch when additional     speculative execution mitigations are in place. This     issue was introduced when the per task/process     conditional STIPB switching was added on top of the     existing SSBD switching. The highest threat from this     vulnerability is to confidentiality.(CVE-2020-10766)

  - A new domain bypass transient execution attack known as     Special Register Buffer Data Sampling (SRBDS) has been     found. This flaw allows data values from special     internal registers to be leaked by an attacker able to     execute code on any core of the CPU. An unprivileged,     local attacker can use this flaw to infer values     returned by affected instructions known to be commonly     used during cryptographic operations that rely on     uniqueness, secrecy, or both.(CVE-2020-0543)

  - In the Linux kernel before 5.4.16, a race condition in     tty->disc_data handling in the slip and slcan line     discipline could lead to a use-after-free, aka     CID-0ace17d56824. This affects drivers/net/slip/slip.c     and drivers/net/can/slcan.c.(CVE-2020-14416)

  - The flow_dissector feature in the Linux kernel 4.3     through 5.x before 5.3.10 has a device tracking     vulnerability, aka CID-55667441c84f. This occurs     because the auto flowlabel of a UDP IPv6 packet relies     on a 32-bit hashrnd value as a secret, and because     jhash (instead of siphash) is used. The hashrnd value     remains the same starting from boot time, and can be     inferred by an attacker. This affects     net/core/flow_dissector.c and related     code.(CVE-2019-18282)

  - The VFIO PCI driver in the Linux kernel through 5.6.13     mishandles attempts to access disabled memory     space.(CVE-2020-12888)

  - In the Linux kernel through 5.7.6, usbtest_disconnect     in drivers/usb/misc/usbtest.c has a memory leak, aka     CID-28ebeb8db770.(CVE-2020-15393)

  - A flaw was found in the ZRAM kernel module, where a     user with a local account and the ability to read the     /sys/class/zram-control/hot_add file can create ZRAM     device nodes in the /dev/ directory. This read     allocates kernel memory and is not accounted for a user     that triggers the creation of that ZRAM device. With     this vulnerability, continually reading the device may     consume a large amount of system memory and cause the     Out-of-Memory (OOM) killer to activate and terminate     random userspace processes, possibly making the system     inoperable.(CVE-2020-10781)

The SUSE Linux Enterprise 12 SP5 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed :

CVE-2020-10768: The prctl() function could be used to enable indirect branch speculation even after it has been disabled. (bnc#1172783)

CVE-2020-10766: A bug in the logic handling could allow an attacker with a local account to disable SSBD protection. (bnc#1172781)

CVE-2020-10767: A IBPB would be disabled when STIBP was not available or when Enhanced Indirect Branch Restricted Speculation (IBRS) was available. This is unexpected behaviour could leave the system open to a spectre v2 style attack (bnc#1172782)

CVE-2020-13974: drivers/tty/vt/keyboard.c had an integer overflow if k_ascii was called several times in a row (bnc#1172775)

CVE-2019-20810: go7007_snd_init did not call snd_card_free for a failure path, which caused a memory leak (bnc#1172458)

The update package also includes non-security fixes. See advisory for details.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - A logic bug flaw was found in Linux kernel before 5.8-rc1 in the implementation of SSBD. A bug in the     logic handling allows an attacker with a local account to disable SSBD protection during a context switch     when additional speculative execution mitigations are in place. This issue was introduced when the per     task/process conditional STIPB switching was added on top of the existing SSBD switching. The highest     threat from this vulnerability is to confidentiality. (CVE-2020-10766)

Note that Nessus relies on the presence of the package as reported by the vendor.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-004240 advisory.
