OESA-2026-1992 qemu security update

QEMU is a FAST! processor emulator using dynamic translation to achieve good emulation speed. Security Fixes: 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...

SUSE CVE-2023-42467

QEMU through 8.0.0 could trigger a division by zero in scsidiskreset in hw/scsi/scsi-disk.c because scsidiskemulatemodeselect does not prevent s-qdev.blocksize from being 256. This stops QEMU and the guest immediately...

QEMU: vhost-vsock: missing virtqueue detach on error can lead to memory leak

A flaw was found in the vhost-vsock device of QEMU. In case of error, an invalid element was not detached from the virtqueue before freeing its memory, leading to memory leakage and other unexpected results...

UBUNTU-CVE-2021-20257

An infinite loop flaw was found in the e1000 NIC emulator of the QEMU. This issue occurs while processing transmits tx descriptors in processtxdesc if various descriptor fields are initialized with invalid values. This flaw allows a guest to consume CPU cycles on the host, resulting in a denial o...

ALPINE-CVE-2017-5931

Integer overflow in hw/virtio/virtio-crypto.c in QEMU aka Quick Emulator allows local guest OS privileged users to cause a denial of service QEMU process crash or possibly execute arbitrary code on the host via a crafted virtio-crypto request, which triggers a heap-based buffer overflow...

QEMU scsi information disclosure vulnerability

QEMU is a simulation processor software developed by French programmer Fabrice Bellard. The software is fast and cross-platform. An information disclosure vulnerability exists in QEMU's scsi. When the program is supported using the MegaRAID SAS 8708EM2 Host Bus Adapter emulator, an attacker can...

UBUNTU-CVE-2013-4535

The virtqueuemapsg function in hw/virtio/virtio.c in QEMU before 1.7.2 allows remote attackers to execute arbitrary files via a crafted savevm image, related to virtio-block or virtio-serial read...
