Astra Linux – Vulnerability in Qemu

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

CVE-2024-47727

In the Linux kernel, the following vulnerability has been resolved: x86/tdx: Fix "in-kernel MMIO" check TDX only supports kernel-initiated MMIO operations. The handlemmio function checks if the VE exception occurred in the kernel and rejects the operation if it did not. However, userspace can...

CVE-2024-46705 drm/xe: reset mmio mappings with devm

In the Linux kernel, the following vulnerability has been resolved: drm/xe: reset mmio mappings with devm Set our various mmio mappings to NULL. This should make it easier to catch something rogue trying to mess with mmio after device removal. For example, we might unmap everything and then start...

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...

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: KVM: leak of uninitialized stack contents to guest

An information leakage issue was found in the way Linux kernel's KVM hypervisor handled page fault exceptions while emulating instructions like VMXON, VMCLEAR, VMPTRLD, and VMWRITE with memory address as an operand. It occurs if the operand is a mmio address, as the returned exception object hold...
