https://notcve.org/view.php?id=CVE-2024-7409
05 Aug 2024 — A flaw was found in the QEMU NBD Server. This vulnerability allows a denial of service (DoS) attack via improper synchronization during socket closure when a client keeps a socket open as the server is taken offline. Red Hat OpenShift Container Platform release 4.16.25 is now available with updates to packages and images that fix several bugs and add enhancements. Issues addressed include bypass and denial of service vulnerabilities. • https://access.redhat.com/security/cve/CVE-2024-7409 • CWE-662: Improper Synchronization •

CVE-2024-4467 – Qemu-kvm: 'qemu-img info' leads to host file read/write
https://notcve.org/view.php?id=CVE-2024-4467
02 Jul 2024 — A flaw was found in the QEMU disk image utility (qemu-img) 'info' command. A specially crafted image file containing a `json:{}` value describing block devices in QMP could cause the qemu-img process on the host to consume large amounts of memory or CPU time, leading to denial of service or read/write to an existing external file.

CVE-2024-4418 – Libvirt: stack use-after-free in virnetclientioeventloop()
https://notcve.org/view.php?id=CVE-2024-4418
08 May 2024 — A race condition leading to a stack use-after-free flaw was found in libvirt. Due to a bad assumption in the virNetClientIOEventLoop() method, the `data` pointer to a stack-allocated virNetClientIOEventData structure ended up being used in the virNetClientIOEventFD callback while the data pointer's stack frame was concurrently being "freed" when returning from virNetClientIOEventLoop(). The 'virtproxyd' daemon can be used to trigger requests. If libvirt is configured with fine-grained access control, this i... • https://access.redhat.com/errata/RHSA-2024:4351 • CWE-416: Use After Free •

CVE-2021-3930 – QEMU: off-by-one error in mode_sense_page() in hw/scsi/scsi-disk.c
https://notcve.org/view.php?id=CVE-2021-3930
10 Dec 2021 — An off-by-one error was found in the SCSI device emulation in QEMU. It could occur while processing MODE SELECT commands in mode_sense_page() if the 'page' argument was set to MODE_PAGE_ALLS (0x3f). A malicious guest could use this flaw to potentially crash QEMU, resulting in a denial of service condition. Se ha encontrado un error "off-by-one" en la emulación de dispositivos SCSI en QEMU.

CVE-2021-3748 – QEMU: virtio-net: heap use-after-free in virtio_net_receive_rcu
https://notcve.org/view.php?id=CVE-2021-3748
28 Oct 2021 — A use-after-free vulnerability was found in the virtio-net device of QEMU. It could occur when the descriptor's address belongs to the non direct access region, due to num_buffers being set after the virtqueue elem has been unmapped. A malicious guest could use this flaw to crash QEMU, resulting in a denial of service condition, or potentially execute code on the host with the privileges of the QEMU process.

CVE-2018-13405 – Linux (Ubuntu) - Other Users coredumps Can Be Read via setgid Directory and killpriv Bypass
https://notcve.org/view.php?id=CVE-2018-13405
06 Jul 2018 — The inode_init_owner function in fs/inode.c in the Linux kernel through 3.16 allows local users to create files with an unintended group ownership, in a scenario where a directory is SGID to a certain group and is writable by a user who is not a member of that group. Here, the non-member can trigger creation of a plain file whose group ownership is that group. The intended behavior was that the non-member can trigger creation of a directory (but not a plain file) whose group ownership is that group.
