USN-6628-1 linux-intel-iotg vulnerabilities

Quentin Minster discovered that a race condition existed in the KSMBD implementation in the Linux kernel when handling sessions operations. A remote attacker could use this to cause a denial of service system crash or possibly execute arbitrary code. CVE-2023-32250, CVE-2023-32252, CVE-2023-32257...

kernel: wifi: mt76: connac: do not check WED status for non-mmio devices

In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: connac: do not check WED status for non-mmio devices WED is supported just for mmio devices, so do not check it for usb or sdio devices. This patch fixes the crash reported below: 21.946627 wlp0s3u1i3: authenticate wi...

kernel: Linux kernel KVM: Memory leak via coalesced MMIO unregistration failure

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM component. This vulnerability occurs when the unregistration of a coalesced Memory-Mapped I/O MMIO device fails, leading to a memory leak. A local attacker could exploit this flaw to consume system memory, potentially causing...

kernel: i2c: piix4: Fix a memory leak in the EFCH MMIO support

In the Linux kernel, the following vulnerability has been resolved: i2c: piix4: Fix a memory leak in the EFCH MMIO support The recently added support for EFCH MMIO regions introduced a memory leak in that code path. The leak is caused by the fact that releaseresource merely removes the resource...

SUSE CVE-2006-1528

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-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-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-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...
