Linux kernel security vulnerabilities

The Linux kernel is the kernel used by the Linux Foundation's open source operating system Linux. A security vulnerability exists in the Linux kernel, which stems from a post-release reuse issue with devmspialloc...

CVE-2021-47047

A flaw was found in the Xilinx ZynqMP GQSPI controller module in the Linux kernel. A crash can occur when a DMA operation is based on an invalid address due to a missing report of an error condition and an unchecked return value, resulting in a denial of service...

CVE-2021-47051

In the Linux kernel, the following vulnerability has been resolved: spi: fsl-lpspi: Fix PM reference leak in lpspipreparexferhardware pmruntimegetsync will increment pm usage counter even it failed. Forgetting to putting operation will result in reference leak here. Fix it by replacing it with...

CVE-2021-47048

In the Linux kernel, the following vulnerability has been resolved: spi: spi-zynqmp-gqspi: fix use-after-free in zynqmpqspiexecop When handling op-addr, it is using the buffer "tmpbuf" which has been freed. This will trigger a use-after-free KASAN warning. Let's use temporary variables to store...

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...
