Denial Of Service (DOS)

Kernel is vulnerable to out of bound reads. A KVM guest using SEV-ES can trigger out-of-bounds reads and writes in the host kernel via the SVMEXITIOIO exit reason...

FreeBSD : wolfssl -- multiple issues (9b9a5f6e-1755-11ed-adef-589cfc01894a)

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the 9b9a5f6e-1755-11ed-adef-589cfc01894a advisory. - AMD EPYC Processors contain an information disclosure vulnerability in the Secure Encrypted...

CVE-2021-26342

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...
