CVE-2021-47047 spi: spi-zynqmp-gqspi: return -ENOMEM if dma_map_single fails

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...

CVE-2021-47047

CVE-2021-47047 concerns the Linux kernel SPI ZynqMP GQSPI driver. The root cause was that dma_map_single failures could lead to using an unmapped address, triggering a crash when reading large flash blocks. The fix adjusts the SPI controller to support a 44-bit DMA address width and to return imm...

CVE-2021-46920

In the Linux kernel, the following vulnerability has been resolved: dmaengine: idxd: Fix clobbering of SWERR overflow bit on writeback Current code blindly writes over the SWERR and the OVERFLOW bits. Write back the bits actually read instead so the driver avoids clobbering the OVERFLOW bit that...

CVE-2021-46917

In the Linux kernel, the following vulnerability has been resolved: dmaengine: idxd: fix wq cleanup of WQCFG registers A pre-release silicon erratum workaround where wq reset does not clear WQCFG registers was leaked into upstream code.

Buffer Overflow

QEMU is vulnerable to Buffer Overflow. The vulnerability is due to an integer underflow, resulting in a buffer overflow, via a TI command when an expected non-DMA transfer length is less than the length of the available FIFO data. This occurs in espdonodma in hw/scsi/esp.c because of an underflow...
