  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 gue

• CVE-2022-0216Aug 26, 2022
  affected < 4.2.1-150200.69.1fixed 4.2.1-150200.69.1

  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-2021-3929Aug 25, 2022
  affected < 4.2.1-150200.79.1fixed 4.2.1-150200.79.1

  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-2022-35414Jul 11, 2022
  affected < 4.2.1-150200.69.1fixed 4.2.1-150200.69.1

  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. NOTE: a third party states that the Non-virtualization Use Case in the qemu.org reference applies here, i.e., "Bugs affecting the non-v

• CVE-2021-3750May 2, 2022
  affected < 4.2.1-150200.79.1fixed 4.2.1-150200.79.1

  A DMA reentrancy issue was found in the USB EHCI controller emulation of QEMU. EHCI does not verify if the Buffer Pointer overlaps with its MMIO region when it transfers the USB packets. Crafted content may be written to the controller's registers and trigger undesirable actions

• CVE-2021-4206Apr 29, 2022
  affected < 4.2.1-150200.69.1fixed 4.2.1-150200.69.1

  A flaw was found in the QXL display device emulation in QEMU. An integer overflow in the cursor_alloc() function can lead to the allocation of a small cursor object followed by a subsequent heap-based buffer overflow. This flaw allows a malicious privileged guest user to crash th

• CVE-2021-4207Apr 29, 2022
  affected < 4.2.1-150200.69.1fixed 4.2.1-150200.69.1

  A flaw was found in the QXL display device emulation in QEMU. A double fetch of guest controlled values `cursor->header.width` and `cursor->header.height` can lead to the allocation of a small cursor object followed by a subsequent heap-based buffer overflow. A malicious privileg

• CVE-2022-1050Mar 29, 2022
  affected < 4.2.1-150200.79.1fixed 4.2.1-150200.79.1

  A flaw was found in the QEMU implementation of VMWare's paravirtual RDMA device. This flaw allows a crafted guest driver to execute HW commands when shared buffers are not yet allocated, potentially leading to a use-after-free condition.

• CVE-2022-26354Mar 16, 2022
  affected < 4.2.1-150200.79.1fixed 4.2.1-150200.79.1
