CVE-2021-4093

CVE-2021-4093 : A flaw in the KVM AMD SEV-ES code allows a malicious VM using SEV-ES to trigger out-of-bounds reads/writes in the host kernel via a VMGEXIT with a string I/O instruction (e.g., outs/ins) using exit reason SVM_EXIT_IOIO. This can crash the host or enable a guest-to-host escape. Aff...

CVE-2021-39298

CVE-2021-39298 concerns AMD SMM (System Management Mode) interrupt handler. The AMD AMD-SB-1027/AMD-SB-1032 entries describe a vulnerability where a highly-privileged adversary could access SMM and achieve arbitrary code execution, potentially bypassing UEFI firmware security measures. Affected c...

AlmaLinux 8 : kernel (ALSA-2021:3548)

The remote AlmaLinux 8 host has packages installed that are affected by a vulnerability as referenced in the ALSA-2021:3548 advisory. - 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 ...

The vulnerability of the Linux operating system’s kernel, related to deficiencies in access control, allows attackers to escalate their privileges.

The vulnerability of the Linux operating system’s kernel is related to improperly applied security restrictions in the KVM AMD code, which is used to support embedded virtualization within SVM. Exploiting this vulnerability can allow attackers to increase their privileges...
