The remote SUSE Linux SLES12 / SLES_SAP12 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:0328-1 advisory.

    This update for the Linux Kernel 4.4.180-94_147 fixes several issues.

    The following security issues were fixed:

    - CVE-2018-25020: Fixed an issue in the BPF subsystem in the Linux kernel mishandled situations with a     long jump over an instruction sequence where inner instructions require substantial expansions into     multiple BPF instructions, leading to an overflow. (bsc#1193575)
    - CVE-2020-3702: Fixed a bug which could be triggered with specifically timed and handcrafted traffic and     cause internal errors in a WLAN device that lead to improper layer 2 Wi-Fi encryption with a consequent     possibility of information disclosure. (bsc#1191193)
    - CVE-2019-0136: Fixed an insufficient access control which allow an unauthenticated user to execute a     denial of service. (bsc#1193157)
    - CVE-2021-42739: The firewire subsystem had a buffer overflow related to drivers/media/firewire/firedtv-     avc.c and drivers/media/firewire/firedtv-ci.c, because avc_ca_pmt mishandled bounds checking     (bsc#1184673).

Tenable has extracted the preceding description block directly from the SUSE security advisory.

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

The version of microvm-kernel installed on the remote host is prior to 4.14.246-200.474. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2MICROVM-KERNEL-4.14-2023-003 advisory.

    A flaw was found in the Linux kernel's implementation of wireless drivers using the Atheros chipsets.  An     attacker within wireless range could send crafted traffic leading to information disclosure.
    (CVE-2020-3702)

    A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when     processing the VMCB (virtual machine control block) provided by the L1 guest to spawn/handle a nested     guest (L2). Due to improper validation of the int_ctl field, this issue could allow a malicious L1 to     enable AVIC support (Advanced Virtual Interrupt Controller) for the L2 guest. As a result, the L2 guest     would be allowed to read/write physical pages of the host, resulting in a crash of the entire system, leak     of sensitive data or potential guest-to-host escape. (CVE-2021-3653)

    A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when     processing the VMCB (virtual machine control block) provided by the L1 guest to spawn/handle a nested     guest (L2). Due to improper validation of the virt_ext field, this issue could allow a malicious L1 to     disable both VMLOAD/VMSAVE intercepts and VLS (Virtual VMLOAD/VMSAVE) for the L2 guest. As a result, the     L2 guest would be allowed to read/write physical pages of the host, resulting in a crash of the entire     system, leak of sensitive data or potential guest-to-host escape. (CVE-2021-3656)

    A flaw was found in the Linux kernel's OverlayFS subsystem in the way the user mounts the TmpFS filesystem     with OverlayFS. This flaw allows a local user to gain access to hidden files that should not be     accessible. (CVE-2021-3732)

    A race problem was seen in the vt_k_ioctl in drivers/tty/vt/vt_ioctl.c in the Linux kernel, which may     cause an out of bounds read in vt as the write access to vc_mode is not protected by lock-in vt_ioctl     (KDSETMDE). The highest threat from this vulnerability is to data confidentiality. (CVE-2021-3753)

    A flaw was found in the Linux kernel, where it incorrectly computes the access permissions of a shadow     page. This issue leads to a missing guest protection page fault. (CVE-2021-38198)

    A flaw was found in the Linux kernel that allows attackers to defeat an ASLR protection mechanism because     it prints a kernel pointer (i.e., the real IOMEM pointer). The highest threat from this vulnerability is     to confidentiality. (CVE-2021-38205)
