The remote Oracle Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2020-3218 advisory.

  - An issue was discovered in drivers/firmware/efi/efi.c in the Linux kernel before 5.4. Incorrect access     permissions for the efivar_ssdt ACPI variable could be used by attackers to bypass lockdown or secure boot     restrictions, aka CID-1957a85b0032. (CVE-2019-20908)

  - An issue was discovered in drivers/acpi/acpi_configfs.c in the Linux kernel before 5.7.7. Injection of     malicious ACPI tables via configfs could be used by attackers to bypass lockdown and secure boot     restrictions, aka CID-75b0cea7bf30. (CVE-2020-15780)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote Ubuntu 18.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-4439-1 advisory.

  - **DISPUTED** An issue was discovered in the efi subsystem in the Linux kernel through 5.1.5.
    phys_efi_set_virtual_address_map in arch/x86/platform/efi/efi.c and efi_call_phys_prolog in     arch/x86/platform/efi/efi_64.c mishandle memory allocation failures. NOTE: This id is disputed as not     being an issue because All the code touched by the referenced commit runs only at boot, before any user     processes are started. Therefore, there is no possibility for an unprivileged user to control it..
    (CVE-2019-12380)

  - An issue was discovered in the Linux kernel through 5.2.13. nbd_genl_status in drivers/block/nbd.c does     not check the nla_nest_start_noflag return value. (CVE-2019-16089)

  - btrfs_root_node in fs/btrfs/ctree.c in the Linux kernel through 5.3.12 allows a NULL pointer dereference     because rcu_dereference(root->node) can be zero. (CVE-2019-19036)

  - relay_open in kernel/relay.c in the Linux kernel through 5.4.1 allows local users to cause a denial of     service (such as relay blockage) by triggering a NULL alloc_percpu result. (CVE-2019-19462)

  - 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)

  - A flaw was found in the Linux kernel's implementation of Userspace core dumps. This flaw allows an     attacker with a local account to crash a trivial program and exfiltrate private kernel data.
    (CVE-2020-10732)

  - 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)

  - 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)

  - A flaw was found in the Linux kernel before 5.8-rc1 in the 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 flaw was found in the Linux Kernel before 5.8-rc1 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)

  - It was discovered that aufs improperly managed inode reference counts in the vfsub_dentry_open() method. A     local attacker could use this vulnerability to cause a denial of service attack. (CVE-2020-11935)

  - An issue was discovered in the Linux kernel 4.4 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 drivers/acpi/acpi_configfs.c in the Linux kernel before 5.7.7. Injection of     malicious ACPI tables via configfs could be used by attackers to bypass lockdown and secure boot     restrictions, aka CID-75b0cea7bf30. (CVE-2020-15780)

  - An issue was discovered in drivers/firmware/efi/efi.c in the Linux kernel before 5.4. Incorrect access     permissions for the efivar_ssdt ACPI variable could be used by attackers to bypass lockdown or secure boot     restrictions, aka CID-1957a85b0032. (CVE-2019-20908)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
