RHEL 8 : qemu-kvm (Unpatched Vulnerability)

low Nessus Plugin ID 198711


The remote Red Hat 8 host is affected by multiple vulnerabilities that will not be patched.


The remote Redhat Enterprise Linux 8 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

- QEMU: ppc64: sPAPR emulator leaks the host hardware identity (CVE-2019-8934)

- The ahci_commit_buf function in ide/ahci.c in QEMU allows attackers to cause a denial of service (NULL dereference) when the command header 'ad->cur_cmd' is null. (CVE-2019-12067)

- hw/ide/pci.c in QEMU before 5.1.1 can trigger a NULL pointer dereference because it lacks a pointer check before an ide_cancel_dma_sync call. (CVE-2020-25743)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.


The vendor has acknowledged the vulnerabilities but no solution has been provided. Refer to the vendor for remediation guidance.
