QEMU vulnerabilities

A flaw in QEMU's virtio-blk device fails to validate input descriptor sizes before writing data. A privileged guest can submit a malformed SCSI request, causing an out-of-bounds write on the host heap memory.

A flaw was found in QEMU where a specially crafted VMDK image could trigger an out-of-bounds read vulnerability. This may lead to a 12-byte leak of sensitive information or a denial of service (DoS) condition.

A stack-based buffer overflow was found in the QEMU e1000 network device. The issue stems from the device's receive code still being able to process a short frame in loopback mode, leading to a buffer overrun in the e1000_receive_iov() function.

QEMU through 8.0.4 accesses a NULL pointer in nvme_directive_receive in hw/nvme/ctrl.c because there is no check for whether an endurance group is configured before checking whether Flexible Data Placement is enabled.

A heap out-of-bounds memory read flaw was found in the virtual NVMe device in QEMU. The QEMU process does not validate an offset provided by the guest before computing a host heap pointer, which can lead to the disclosure of arbitrary heap memory relative to an allocated buffer.
