UBUNTU-CVE-2021-47057

In the Linux kernel, the following vulnerability has been resolved: crypto: sun8i-ss - Fix memory leak of object d when dmaiv fails to map In the case where the dmaiv mapping fails, the return error path leaks the memory allocated to object d. Fix this by adding a new error return label and jumpi...

CVE-2021-47064

In the Linux kernel, the following vulnerability has been resolved: mt76: fix potential DMA mapping leak With buf uninitialized in mt76dmatxqueueskbraw, its field skipunmap could potentially inherit a non-zero value from stack garbage. If this happens, it will cause DMA mappings for MCU command...

CVE-2021-47064

A memory leak vulnerability exists in the Linux kernel 's mt76 driver. Specifically, an uninitialized buffer in the mt76_dma_tx_queue_skb_raw function could cause its skip_unmap field to inherit a non-zero value from stack garbage. If this occurs, DMA mappings for MCU command frames will fail to ...

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-2021-47047

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...
