SUSE CVE-2021-47140

In the Linux kernel, the following vulnerability has been resolved: iommu/amd: Clear DMA ops when switching domain Since commit 08a27c1c3ecf "iommu: Add support to change default domain of an iommu group" a user can switch a device between IOMMU and direct DMA through sysfs. This doesn't work for...

DEBIAN-CVE-2021-47137

In the Linux kernel, the following vulnerability has been resolved: net: lantiq: fix memory corruption in RX ring In a situation where memory allocation or dma mapping fails, an invalid address is programmed into the descriptor. This can lead to memory corruption. If the memory allocation fails,...

OESA-2024-1312 qemu security update

QEMU is a FAST! processor emulator using dynamic translation to achieve good emulation speed. Security Fixes: A DMA reentrancy issue leading to a use-after-free error was found in the e1000e NIC emulation code in QEMU. This issue could allow a privileged guest user to crash the QEMU process on th...

UBUNTU-CVE-2023-52492

In the Linux kernel, the following vulnerability has been resolved: dmaengine: fix NULL pointer in channel unregistration function dmaasyncdevicechannelregister can fail. In case of failure, chan-local is freed with freepercpu, and chan-local is nullified. When dmaasyncdeviceunregister is called...

SUSE CVE-2023-52517

In the Linux kernel, the following vulnerability has been resolved: spi: sun6i: fix race between DMA RX transfer completion and RX FIFO drain Previously the transfer complete IRQ immediately drained to RX FIFO to read any data remaining in FIFO to the RX buffer. This behaviour is correct when...

SUSE CVE-2021-47078

In the Linux kernel, the following vulnerability has been resolved: RDMA/rxe: Clear all QP fields if creation failed rxeqpdocleanup relies on valid pointer values in QP for the properly created ones, but in case rxeqpfrominit failed it was filled with garbage and caused tot the following error...

DEBIAN-CVE-2023-52511

In the Linux kernel, the following vulnerability has been resolved: spi: sun6i: reduce DMA RX transfer width to single byte Through empirical testing it has been determined that sometimes RX SPI transfers with DMA enabled return corrupted data. This is down to single or even multiple bytes lost...

SUSE CVE-2021-47047

In the Linux kernel, the following vulnerability has been resolved: spi: spi-zynqmp-gqspi: return -ENOMEM if dmamapsingle fails The spi controller supports 44-bit address space on AXI in DMA mode, so set dmaaddrt width to 44-bit to avoid using a swiotlb mapping. In addition, if dmamapsingle fails...
