Name of the Vulnerable Software and Affected Versions: AMD CPUs affected versions not specified Description: The issue is related to speculative execution in AMD CPUs, which may allow data leakage by transiently executing beyond unconditional direct branches. This could potentially lead to the...

Important: kernel

Issue Overview: A buffer overflow flaw in the Linux kernel BPF subsystem was found in the way users run BPF with long jump over an instruction sequence where inner instructions require substantial expansions into multiple BPF instructions. A local user could use this flaw to crash the system or...

Citrix Hypervisor Security Update

An issue has been identified in AMD CPU hardware that may allow code in a guest VM to infer the value of in-memory data in other guest VMs. Although this is not an issue in the Citrix Hypervisor product itself, Citrix is releasinghotfixes that include mitigations for this hardware issue. This iss...

CVE-2021-3656

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 "virtext" field, this issue could allow a malicious...

CVE-2021-3656

CVE-2021-3656 describes a flaw in the KVM hypervisor for AMD processors where the L1 guest can provide a VMCB with an improperly validated virt_ext field, allowing the L1 to disable VMLOAD/VMSAVE intercepts and VLS for the L2 guest. This enables the L2 guest to read/write portions of the host’s p...

A flaw was found in the KVM's AMD code for supporting the Secure Encrypted Virtualization-Encrypted State (SEV-ES). A KVM guest using SEV-ES can trigger out-of-bounds reads and writes in the host kernel via a malicious VMGEXIT for a string I/O instruction (for example outs or ins) using the exit reason SVM_EXIT_IOIO. This issue results in a crash of the entire system or a potential guest-to-host escape scenario.
