CVE-2023-52455

In the Linux kernel, the following vulnerability has been resolved: iommu: Don't reserve 0-length IOVA region When the bootloader/firmware doesn't setup the framebuffers, their address and size are 0 in "iommu-addresses" property. If IOVA region is reserved with 0 length, then it ends up corrupti...

Design/Logic Flaw

Vyper is a Pythonic Smart Contract Language for the EVM. There is an error in the stack management when compiling the IR for sha364. Concretely, the height variable is miscalculated. The vulnerability can't be triggered without writing the IR by hand that is, it cannot be triggered from regular...

CVE-2023-34326

The caching invalidation guidelines from the AMD-Vi specification 48882—Rev 3.07-PUB—Oct 2022 is incorrect on some hardware, as devices will malfunction see stale DMA mappings if some fields of the DTE are updated but the IOMMU TLB is not flushed. Such stale DMA mappings can point to memory range...

CVE-2023-34326

CVE-2023-34326 concerns AMD-Vi (IOMMU) caching invalidation. The AMD-Vi specification guides improper invalidation: if DTE fields are updated but the IOMMU TLB is not flushed, devices may cause stale DMA mappings. These mappings can reference memory ranges not owned by the guest, potentially expo...

Denial Of Service (DoS)

xen is vulnerable to Denial Of Service DoS. The vulnerability exists due to incorrect caching invalidation guidelines in the AMD-Vi specification 48882—Rev 3.07-PUB—Oct 2022 on certain hardware. Updating specific fields of the DTE without flushing the IOMMU TLB can lead to device malfunctions e.g...

kernel: i40e: Fix DMA mappings leak

A DMA mapping leak vulnerability was found in the Intel i40e network driver in the Linux kernel. During reallocation of RX buffers when changing ring parameters via ethtool, DMA mappings are not properly cleaned up before creating new ones. Repeated ring size changes can exhaust DMA resources,...
