| CVE-2023-3180 | 0.00 | — | 0.00 | Aug 3, 2023 | A flaw was found in the QEMU virtual crypto device while handling data encryption/decryption requests in virtio_crypto_handle_sym_req. There is no check for the value of `src_len` and `dst_len` in virtio_crypto_sym_op_helper, potentially leading to a heap buffer overflow when… | |||
| CVE-2023-1386 | 0.00 | — | 0.00 | Jul 24, 2023 | A flaw was found in the 9p passthrough filesystem (9pfs) implementation in QEMU. When a local user in the guest writes an executable file with SUID or SGID, none of these privileged bits are correctly dropped. As a result, in rare circumstances, this flaw could be used by… | |||
| CVE-2023-3354 | 0.00 | — | 0.02 | Jul 11, 2023 | A flaw was found in the QEMU built-in VNC server. When a client connects to the VNC server, QEMU checks whether the current number of connections crosses a certain threshold and if so, cleans up the previous connection. If the previous connection happens to be in the handshake… | |||
| CVE-2023-0664 | 0.00 | — | 0.00 | Mar 29, 2023 | A flaw was found in the QEMU Guest Agent service for Windows. A local unprivileged user may be able to manipulate the QEMU Guest Agent's Windows installer via repair custom actions to elevate their privileges on the system. | |||
| CVE-2023-1544 | 0.00 | — | 0.00 | Mar 23, 2023 | A flaw was found in the QEMU implementation of VMWare's paravirtual RDMA device. This flaw allows a crafted guest driver to allocate and initialize a huge number of page tables to be used as a ring of descriptors for CQ and async events, potentially leading to an out-of-bounds… | |||
| CVE-2023-0330 | 0.00 | — | 0.00 | Mar 6, 2023 | A vulnerability in the lsi53c895a device affects the latest version of qemu. A DMA-MMIO reentrancy problem may lead to memory corruption bugs like stack overflow or use-after-free. | |||
| CVE-2022-4172 | 0.00 | — | 0.00 | Nov 29, 2022 | An integer overflow and buffer overflow issues were found in the ACPI Error Record Serialization Table (ERST) device of QEMU in the read_erst_record() and write_erst_record() functions. Both issues may allow the guest to overrun the host buffer allocated for the ERST memory… | |||
| CVE-2022-4144 | 0.00 | — | 0.00 | Nov 29, 2022 | An out-of-bounds read flaw was found in the QXL display device emulation in QEMU. The qxl_phys2virt() function does not check the size of the structure pointed to by the guest physical address, potentially reading past the end of the bar space into adjacent pages. A malicious… | |||
| CVE-2022-3872 | 0.00 | — | 0.01 | Nov 7, 2022 | An off-by-one read/write issue was found in the SDHCI device of QEMU. It occurs when reading/writing the Buffer Data Port Register in sdhci_read_dataport and sdhci_write_dataport, respectively, if data_count == block_size. A malicious guest could use this flaw to crash the QEMU… | |||
| CVE-2022-3165 | 0.00 | — | 0.01 | Oct 17, 2022 | An integer underflow issue was found in the QEMU VNC server while processing ClientCutText messages in the extended format. A malicious client could use this flaw to make QEMU unresponsive by sending a specially crafted payload message, resulting in a denial of service. | |||
| CVE-2022-2962 | 0.00 | — | 0.00 | Sep 13, 2022 | A DMA reentrancy issue was found in the Tulip device emulation in QEMU. When Tulip reads or writes to the rx/tx descriptor or copies the rx/tx frame, it doesn't check whether the destination address is its own MMIO address. This can cause the device to trigger MMIO handlers… | |||
| CVE-2022-0358 | 0.00 | — | 0.00 | Aug 29, 2022 | A flaw was found in the QEMU virtio-fs shared file system daemon (virtiofsd) implementation. This flaw is strictly related to CVE-2018-13405. A local guest user can create files in the directories shared by virtio-fs with unintended group ownership in a scenario where a… | |||
| CVE-2021-3735 | 0.00 | — | 0.00 | Aug 26, 2022 | A deadlock issue was found in the AHCI controller device of QEMU. It occurs on a software reset (ahci_reset_port) while handling a host-to-device Register FIS (Frame Information Structure) packet from the guest. A privileged user inside the guest could use this flaw to hang the… | |||
| CVE-2022-0216 | 0.00 | — | 0.00 | Aug 26, 2022 | A use-after-free vulnerability was found in the LSI53C895A SCSI Host Bus Adapter emulation of QEMU. The flaw occurs while processing repeated messages to cancel the current SCSI request via the lsi_do_msgout function. This flaw allows a malicious privileged user within the guest… | |||
| CVE-2021-3929 | 0.00 | — | 0.01 | Aug 25, 2022 | A DMA reentrancy issue was found in the NVM Express Controller (NVME) emulation in QEMU. This CVE is similar to CVE-2021-3750 and, just like it, when the reentrancy write triggers the reset function nvme_ctrl_reset(), data structs will be freed leading to a use-after-free issue.… | |||
| CVE-2021-4158 | 0.00 | — | 0.00 | Aug 24, 2022 | A NULL pointer dereference issue was found in the ACPI code of QEMU. A malicious, privileged user within the guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition. | |||
| CVE-2020-14394 | 0.00 | — | 0.00 | Aug 17, 2022 | An infinite loop flaw was found in the USB xHCI controller emulation of QEMU while computing the length of the Transfer Request Block (TRB) Ring. This flaw allows a privileged guest user to hang the QEMU process on the host, resulting in a denial of service. | |||
| CVE-2022-35414 | 0.00 | — | 0.01 | Jul 11, 2022 | softmmu/physmem.c in QEMU through 7.0.0 can perform an uninitialized read on the translate_fail path, leading to an io_readx or io_writex crash.
