SUSE CVE-2017-7995

Xen PV guest before Xen 4.3 checked access permissions to MMIO ranges only after accessing them, allowing host PCI device space memory reads, leading to information disclosure. This is an error in the getuser function. NOTE: the upstream Xen Project considers versions before 4.5.x to be EOL...

SUSE CVE-2017-17741

The KVM implementation in the Linux kernel through 4.14.7 allows attackers to obtain potentially sensitive information from kernel memory, aka a writemmio stack-based out-of-bounds read, related to arch/x86/kvm/x86.c and include/trace/events/kvm.h...

SUSE CVE-2019-14821

An out-of-bounds access issue was found in the Linux kernel, all versions through 5.3, in the way Linux kernel's KVM hypervisor implements the Coalesced MMIO write operation. It operates on an MMIO ring buffer 'struct kvmcoalescedmmio' object, wherein write indices 'ring-first' and 'ring-last'...

SUSE CVE-2019-20808

In QEMU 4.1.0, an out-of-bounds read flaw was found in the ATI VGA implementation. It occurs in the aticursordefine routine while handling MMIO write operations through the atimmwrite callback. A malicious guest could abuse this flaw to crash the QEMU process, resulting in a denial of service...

SUSE CVE-2020-15859

QEMU 4.2.0 has a use-after-free in hw/net/e1000ecore.c because a guest OS user can trigger an e1000e packet with the data's address set to the e1000e's MMIO address...

SUSE CVE-2020-27821

A flaw was found in the memory management API of QEMU during the initialization of a memory region cache. This issue could lead to an out-of-bounds write access to the MSI-X table while performing MMIO operations. A guest user may abuse this flaw to crash the QEMU process on the host, resulting i...

SUSE CVE-2021-3638

An out-of-bounds memory access flaw was found in the ATI VGA device emulation of QEMU. This flaw occurs in the ati2dblt routine while handling MMIO write operations when the guest provides invalid values for the destination display parameters. A malicious guest could use this flaw to crash the QE...

SUSE CVE-2021-3750

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 such as reset whi...

SUSE CVE-2023-0330

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...
