Qemu-kvm: heap buffer overflow in virtio-blk scsi request handling
A flaw was found in QEMU's virtio-blk device. The issue arises because the device does not properly validate the size of input descriptors before writing data. A malicious guest with high privileges could exploit this vulnerability by submitting a malformed v…

grant table v2 race in status page mapping
The adjustments made for XSA-379 as well as those subsequently becoming XSA-387 still left a race window, when a HVM or PVH guest does a grant table version change from v2 to v1 in parallel with mapping the status page(s) via XENMEM_add_to_physmap. Some of th…

Xenstored DoS via XS_RESET_WATCHES command
Any guest can cause xenstored to crash by issuing a XS_RESET_WATCHES command within a transaction due to an assert() triggering. In case xenstored was built with NDEBUG #defined nothing bad will happen, as assert() is doing nothing in this case. Note that the…

Xenstored DoS by unprivileged domain
Any guest issuing a Xenstore command accessing a node using the (illegal) node path "/local/domain/", will crash xenstored due to a clobbered error indicator in xenstored when verifying the node path. Note that the crash is forced via a failing assert() state…

Use after free of paging structures in EPT
The Intel EPT paging code uses an optimization to defer flushing of any cached EPT state until the p2m lock is dropped, so that multiple modifications done under the same locked region only issue a single flush. Freeing of paging structures however is not def…

Critical 9.1
Angeet ES3 KVM OS command injection
The Angeet ES3 KVM does not properly sanitize user-supplied variables parsed by the 'cfg.lua' script, allowing an authenticated attacker to execute OS-level commands.
-
High 7.5
Angeet ES3 KVM unauthenticated arbitrary file write
The Angeet ES3 KVM allows a remote, unauthenticated attacker to write arbitrary files, including configuration files or system binaries. Modified configuration files or system binaries could allow an attacker to take complete control of a vulnerable system.

Low 3.7
GL-iNet Comet (GL-RM1) KVM insufficient certificate validation
The GL-iNet Comet (GL-RM1) KVM connects to a GL-iNet site during boot-up to provision client and CA certificates. The GL-RM1 does not verify certificates used for this connection, allowing an attacker-in-the-middle to serve invalid client and CA certificates.…

High 7.5
GL-iNet Comet (GL-RM1) KVM insufficient login rate-limiting
The GL-iNet Comet (GL-RM1) KVM web interface does not limit login requests, enabling brute-force attempts to guess credentials.
-
Medium 6.8
GL-iNet Comet (GL-RM1) KVM unauthenticated root access via UART serial console
The GL-iNet Comet (GL-RM1) KVM before 1.8.2 does not require authentication on the UART serial console. This attack requires physically opening the device and connecting to the UART pins.
-
Medium 4.7
GL-iNet Comet (GL-RM1) KVM insufficient firmware verification
The GL-iNet Comet (GL-RM1) KVM before version 1.8.2 does not sufficiently verify the authenticity of uploaded firmware files. An attacker-in-the-middle or a compromised update server could modify the firmware and the corresponding MD5 hash to pass verificatio…

Qemu-kvm: heap buffer out-of-bounds read in vmdk compressed grain parsing
A flaw was found in QEMU. A specially crafted VMDK image could trigger an out-of-bounds read vulnerability, potentially leading to a 12-byte leak of sensitive information or a denial of service condition (DoS).

Qemu-kvm: heap off-by-one in kvm xen physdevop_map_pirq
An off-by-one error was found in QEMU's KVM Xen guest support. A malicious guest could use this flaw to trigger out-of-bounds heap accesses in the QEMU process via the emulated Xen physdev hypercall interface, leading to a denial of service or potential memor…

Qemu-kvm: uefi-vars: information disclosure vulnerability in uefi_vars_write callback
A flaw was found in QEMU in the uefi-vars virtual device. When the guest writes to register UEFI_VARS_REG_BUFFER_SIZE, the .write callback `uefi_vars_write` is invoked. The function allocates a heap buffer without zeroing the memory, leaving the buffer filled…

Qemu-kvm: unbounded allocation in virtio-crypto
A flaw was found in the virtio-crypto device of QEMU. A malicious guest operating system can exploit a missing length limit in the AKCIPHER path, leading to uncontrolled memory allocation. This can result in a denial of service (DoS) on the host system by cau…

terraform-provider-proxmox has insecure sudo recommendation in the documentation
Terraform / OpenTofu Provider adds support for Proxmox Virtual Environment. Prior to version 0.93.1, in the SSH configuration documentation, the sudoer line suggested is insecure and can result in escaping the folder using ../, allowing any files on the syste…

x86: incomplete IBPB for vCPU isolation
In the context switch logic Xen attempts to skip an IBPB in the case of a vCPU returning to a CPU on which it was the previous vCPU to run. While safe for Xen's isolation between vCPUs, this prevents the guest kernel correctly isolating between tasks. Conside…

x86: buffer overrun with shadow paging + tracing
Shadow mode tracing code uses a set of per-CPU variables to avoid cumbersome parameter passing. Some of these variables are written to with guest controlled data, of guest controllable size. That size can be larger than the variable, and bounding of the write…
