Astra Linux – Vulnerability in Qemu

An integer overflow issue was identified in the vmxnet3 NIC emulator of QEMU for versions up to v5.2.0. This issue can occur if a guest provides invalid values for the rx/tx queue size or other NIC parameters. A privileged guest user may exploit this flaw to crash the QEMU process on the host,...

Astra Linux – Vulnerability in Qemu

A flaw was discovered in the QEMU implementation of VMWare’s paravirtual RDMA device. The issue arises when handling the “PVRDMACMDCREATEMR” command due to improper memory remapping mremap. This flaw allows a malicious guest to crash the QEMU process on the host. The greatest threat posed by this...

Astra Linux – Vulnerability in Qemu

A reentrancy issue related to DMA was discovered in the USB EHCI controller emulation of QEMU. EHCI does not verify whether the Buffer Pointer overlaps with its MMIO region when transferring USB packets. Crafted content may be written to the controller’s registers, potentially triggering...

Astra Linux – Vulnerability in Qemu

A heap buffer overflow was discovered in the floppy disk emulator of QEMU up to version 6.0.0 inclusive. This issue could occur in the fdctrltransferhandler function in the hw/block/fdc.c file, during the processing of DMA read data transfers from the floppy drive to the guest system. A privilege...

Astra Linux – Vulnerability in Qemu

A use-after-free vulnerability was discovered in the LSI53C895A SCSI Host Bus Adapter emulation in QEMU. The flaw occurs during the processing of repeated messages to cancel the current SCSI request using the lsidomsgout function. This flaw allows a malicious privileged user within the guest to...

Astra Linux – Vulnerability in Qemu

A reentrancy issue related to DMA was discovered in the Tulip device emulation in QEMU. When Tulip reads from or writes to the rx/tx descriptor, or copies a rx/tx frame, it does not check whether the destination address is its own MMIO address. This can cause the device to trigger MMIO handlers...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: KVM: SVM: Get source vCPUs from source VM for SEV-ES intrahost migration Fix a goof where KVM tries to grab source vCPUs from the destination VM when doing intrahost migration. Grabbing the wrong vCPU not only hoses the guest, it...

Astra Linux – Vulnerability in Qemu

Integer overflows and buffer overflows were identified in the ACPI Error Record Serialization Table ERST device of QEMU, within the readerstrecord and writeerstrecord functions. Both issues may allow the guest to exceed the host buffer allocated for the ERST memory device. A malicious guest could...

Astra Linux – Vulnerability in Qemu

A flaw was discovered in the QXL display device emulation in QEMU. An integer overflow in the cursoralloc function can lead to the allocation of a small cursor object, followed by a subsequent heap-based buffer overflow. This flaw allows a malicious privileged guest user to crash the QEMU process...

Astra Linux – Vulnerability in Qemu

A double-free vulnerability was identified in QEMU virtio devices virtio-gpu, virtio-serial-bus, virtio-crypto. The memreentrancyguard flag does not provide sufficient protection against reentrancy issues related to DMA operations. This vulnerability could allow a malicious privileged guest user ...

Astra Linux – Vulnerability in Qemu

A flaw was discovered in the virtio-net device in QEMU. When the RSS feature is enabled on the virtio-net network card, the indirectionstable data within RSS becomes controllable. Setting values that are excessively large may lead to an index out-of-bounds issue, potentially resulting in a heap...

Astra Linux – Vulnerability in Linux 5.15

A race condition in the x86 KVM subsystem within the Linux kernel, as of 6.1-rc6, allows guest OS users to cause a denial of service host OS crash or host OS memory corruption when nested virtualization is enabled and the TDP MMU is also enabled...

Astra Linux – Vulnerability in Qemu

A reentrancy issue was discovered in the NVM Express Controller NVME emulation in QEMU. This CVE is similar to CVE-2021-3750. Just like in that case, when the reentrancy trigger the reset function nvmectrlreset, data structures will be freed, leading to a use-after-free vulnerability. A malicious...

Astra Linux – Vulnerability in Qemu

A flaw was discovered in QEMU. An assertion failure occurred in the usbepget function in hw/net/core.c when attempting to retrieve the USB endpoint from a USB device. This flaw may allow a malicious unprivileged guest user to crash the QEMU process on the host and cause a denial of service...

Astra Linux – Vulnerability in Linux, Linux 5.10

A issue was discovered in the Linux kernel for PowerPC before version 5.14.15. It allows a malicious KVM guest to crash the host, when the host is running on Power8, due to a bug in the implementation of arch/powerpc/kvm/book3shvrmhandlers.S, which handles the values of the SRR1 register...
