Synopsis

The remote SUSE host is missing one or more security updates.

Description

The remote SUSE Linux SLED12 / SLES12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:2647-1 advisory.

- arch/powerpc/kvm/book3s_rtas.c in the Linux kernel through 5.13.5 on the powerpc platform allows KVM guest OS users to cause host OS memory corruption via rtas_args.nargs, aka CID-f62f3c20647e. (CVE-2021-37576)

- In l2tp_session_delete and related functions of l2tp_core.c, there is possible memory corruption due to a use after free. This could lead to local escalation of privilege with System execution privileges needed.

A-152735806 (CVE-2020-0429)

- An issue was discovered in the Linux kernel before 5.8.1. net/bluetooth/hci_event.c has a slab out-of- bounds read in hci_extended_inquiry_result_evt, aka CID-51c19bf3d5cf. (CVE-2020-36386)

- A NULL pointer dereference flaw was found in the Linux kernel's IEEE 802.15.4 wireless networking subsystem in the way the user closes the LR-WPAN connection. This flaw allows a local user to crash the system. The highest threat from this vulnerability is to system availability. (CVE-2021-3659)

- An issue was discovered in Linux: KVM through Improper handling of VM_IO|VM_PFNMAP vmas in KVM can bypass RO checks and can lead to pages being freed while still accessible by the VMM and guest. This allows users with the ability to start and control a VM to read/write random pages of memory and can result in local privilege escalation. (CVE-2021-22543)

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

Solution

Update the affected packages.
