CVE-2023-6683 2 Qemu, Redhat 3 Qemu, Advanced Virtualization, Enterprise Linux 2026-02-25 6.5 Medium
A flaw was found in the QEMU built-in VNC server while processing ClientCutText messages. The qemu_clipboard_request() function can be reached before vnc_server_cut_text_caps() was called and had the chance to initialize the clipboard peer, leading to a NULL pointer dereference. This could allow a malicious authenticated VNC client to crash QEMU and trigger a denial of service.
CVE-2023-5088 2 Qemu, Redhat 3 Qemu, Advanced Virtualization, Enterprise Linux 2026-02-25 6.4 Medium
A bug in QEMU could cause a guest I/O operation otherwise addressed to an arbitrary disk offset to be targeted to offset 0 instead (potentially overwriting the VM's boot code). This could be used, for example, by L2 guests with a virtual disk (vdiskL2) stored on a virtual disk of an L1 (vdiskL1) hypervisor to read and/or write data to LBA 0 of vdiskL1, potentially gaining control of L1 at its next reboot.
CVE-2021-39261 3 Debian, Redhat, Tuxera 4 Debian Linux, Advanced Virtualization, Enterprise Linux and 1 more 2025-12-05 6.7 Medium
A crafted NTFS image can cause a heap-based buffer overflow in ntfs_compressed_pwrite in NTFS-3G < 2021.8.22.
CVE-2021-33287 4 Debian, Fedoraproject, Redhat and 1 more 5 Debian Linux, Fedora, Advanced Virtualization and 2 more 2025-12-03 6.7 Medium
In NTFS-3G versions < 2021.8.22, when specially crafted NTFS attributes are read in the function ntfs_attr_pread_i, a heap buffer overflow can occur and allow for writing to arbitrary memory or denial of service of the application.
CVE-2021-33285 4 Debian, Fedoraproject, Redhat and 1 more 5 Debian Linux, Fedora, Advanced Virtualization and 2 more 2025-12-03 6.7 Medium
In NTFS-3G versions < 2021.8.22, when a specially crafted NTFS attribute is supplied to the function ntfs_get_attribute_value, a heap buffer overflow can occur allowing for memory disclosure or denial of service. The vulnerability is caused by an out-of-bound buffer access which can be triggered by mounting a crafted ntfs partition. The root cause is a missing consistency check after reading an MFT record : the "bytes_in_use" field should be less than the "bytes_allocated" field. When it is not, the parsing of the records proceeds into the wild.

CVE-2024-8354 2 Qemu, Redhat 3 Qemu, Advanced Virtualization, Enterprise Linux 2025-11-08 5.5 Medium
A flaw was found in QEMU. An assertion failure was present in the usb_ep_get() function in hw/net/core.c when trying to get 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 condition.
CVE-2023-5215 1 Redhat 3 Advanced Virtualization, Enterprise Linux, Libnbd 2025-11-08 5.3 Medium
A flaw was found in libnbd. A server can reply with a block size larger than 2^63 (the NBD spec states the size is a 64-bit unsigned value). This issue could lead to an application crash or other unintended behavior for NBD clients that doesn't treat the return value of the nbd_get_size() function correctly.
CVE-2024-8235 1 Redhat 3 Advanced Virtualization, Enterprise Linux, Libvirt 2025-11-08 6.2 Medium
A flaw was found in libvirt. A refactor of the code fetching the list of interfaces for multiple APIs introduced a corner case on platforms where allocating 0 bytes of memory results in a NULL pointer. This corner case would lead to a NULL-pointer dereference and subsequent crash of virtinterfaced. This issue could allow clients connecting to the read-only socket to crash the virtinterfaced daemon.
