Astra Linux – Vulnerability in Qemu
A flaw was discovered in the virtio-fs shared file system daemon virtiofsd of QEMU. The new ‘xattrmap’ option may cause the ‘security.capability’ xattr in the guest to not be dropped when writing files, potentially allowing a modified, privileged executable to be executed within the guest. In rar...

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 virtio-blk SCSI request, leading to an...

The vulnerability of the `virtio_snd_pcm_in_cb` function in the `hw/audio/virtio-snd.c` component of the QEMU hardware emulation software allows a hacker to trigger a service failure.
The vulnerability of the virtiosndpcmincb function in the hw/audio/virtio-snd.c component of the QEMU hardware emulation software is related to the issue of writing operations outside of the buffer boundaries in memory. Exploiting this vulnerability can allow an attacker to cause a system failure...
The vulnerability in the block/vmdk.c component of the QEMU hardware emulation software allows a hacker to cause a system failure.
The vulnerability of the block/vmdk.c component of the QEMU hardware emulation software is related to reading data from beyond the permissible buffer size. Exploiting this vulnerability can allow an attacker to cause a service failure using a specially created VMDK image...
