SUSE CVE-2013-2212

The vmxsetucmode function in Xen 3.3 through 4.3, when disabling caches, allows local HVM guests with access to memory mapped I/O regions to cause a denial of service CPU consumption and possibly hypervisor or guest kernel panic via a crafted GFN range...

SUSE CVE-2013-4355

Xen 4.3.x and earlier does not properly handle certain errors, which allows local HVM guests to obtain hypervisor stack memory via a 1 port or 2 memory mapped I/O write or 3 other unspecified operations related to addresses without associated memory...

SUSE CVE-2014-7842

Race condition in arch/x86/kvm/x86.c in the Linux kernel before 3.17.4 allows guest OS users to cause a denial of service guest OS crash via a crafted application that performs an MMIO transaction or a PIO transaction to trigger a guest userspace emulation error report, a similar issue to...

SUSE CVE-2014-8867

The acceleration support for the "REP MOVS" instruction in Xen 4.4.x, 3.2.x, and earlier lacks properly bounds checking for memory mapped I/O MMIO emulated in the hypervisor, which allows local HVM guests to cause a denial of service host crash via unspecified vectors...

SUSE CVE-2016-2270

Xen 4.6.x and earlier allows local guest administrators to cause a denial of service host reboot via vectors related to multiple mappings of MMIO pages with different cachability settings...

SUSE CVE-2016-10741

In the Linux kernel before 4.9.3, fs/xfs/xfsaops.c allows local users to cause a denial of service system crash because there is a race condition between direct and memory-mapped I/O associated with a hole that is handled with BUGON instead of an I/O failure...

SUSE CVE-2017-10922

The grant-table feature in Xen through 4.8.x mishandles MMIO region grant references, which allows guest OS users to cause a denial of service loss of grant trackability, aka XSA-224 bug 3...

SUSE CVE-2020-12829

In QEMU through 5.0.0, an integer overflow was found in the SM501 display driver implementation. This flaw occurs in the COPYAREA macro while handling MMIO write operations through the sm5012denginewrite callback. A local attacker could abuse this flaw to crash the QEMU process in sm5012doperatio...

SUSE CVE-2020-13754

hw/pci/msix.c in QEMU 4.2.0 allows guest OS users to trigger an out-of-bounds access via a crafted address in an msi-x mmio operation...

SUSE CVE-2022-2962

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 multiple times, possib...

kernel: tcp: fix page frag corruption on page fault

A vulnerability was found in the Linux kernel's TCP subsystem in the tcpsendmsglocked function, which can lead to page fragment corruption during a page fault, which occurs when a TCP stream experiences nested access to the task page fragment due to a page fault while handling memory-mapped...
