The remote SUSE Linux SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:1846-1 advisory.

  - Failure to flush the Translation Lookaside Buffer (TLB) of the I/O memory management unit (IOMMU) may lead     an IO device to write to memory it should not be able to access, resulting in a potential loss of     integrity. (CVE-2021-26312, CVE-2021-26348)

  - A bug in AMD CPU's core logic may allow for an attacker, using specific code from an unprivileged VM, to     trigger a CPU core hang resulting in a potential denial of service. AMD believes the specific code     includes a specific x86 instruction sequence that would not be generated by compilers. (CVE-2021-26339)

  - In SEV guest VMs, the CPU may fail to flush the Translation Lookaside Buffer (TLB) following a particular     sequence of operations that includes creation of a new virtual machine control block (VMCB). The failure     to flush the TLB may cause the microcode to use stale TLB translations which may allow for disclosure of     SEV guest memory contents. Users of SEV-ES/SEV-SNP guest VMs are not impacted by this vulnerability.
    (CVE-2021-26342)

  - Failure to validate the integer operand in ASP (AMD Secure Processor) bootloader may allow an attacker to     introduce an integer overflow in the L2 directory table in SPI flash resulting in a potential denial of     service. (CVE-2021-26347)

  - Failure to assign a new report ID to an imported guest may potentially result in an SEV-SNP guest VM being     tricked into trusting a dishonest Migration Agent (MA). (CVE-2021-26349)

  - A TOCTOU race condition in SMU may allow for the caller to obtain and manipulate the address of a message     port register which may result in a potential denial of service. (CVE-2021-26350)

  - Insufficient bounds checking in an SMU mailbox register could allow an attacker to potentially read     outside of the SRAM address range which could result in an exception handling leading to a potential     denial of service. (CVE-2021-26364)

  - Insufficient bound checks related to PCIE in the System Management Unit (SMU) may result in access to an     invalid address space that could result in denial of service. (CVE-2021-26372)

  - Insufficient bound checks in the System Management Unit (SMU) may result in a system voltage malfunction     that could result in denial of resources and/or possibly denial of service. (CVE-2021-26373)

  - Insufficient General Purpose IO (GPIO) bounds check in System Management Unit (SMU) may result in     access/updates from/to invalid address space that could result in denial of service. (CVE-2021-26375)

  - Insufficient checks in System Management Unit (SMU) FeatureConfig may result in reenabling features     potentially resulting in denial of resources and/or denial of service. (CVE-2021-26376)

  - Insufficient bound checks in the System Management Unit (SMU) may result in access to an invalid address     space that could result in denial of service. (CVE-2021-26378)

  - Improper validation of the BIOS directory may allow for searches to read beyond the directory table copy     in RAM, exposing out of bounds memory contents, resulting in a potential denial of service.
    (CVE-2021-26388)

  - An attacker with access to a malicious hypervisor may be able to infer data values used in a SEV guest on     AMD CPUs by monitoring ciphertext values over time. (CVE-2021-46744)

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