CVE-2023-52511

CVE-2023-52511 (Linux kernel, spi sun6i) : The issue stems from RX SPI transfers with DMA enabled where data could be corrupted during DMA to memory when transfers span more than a single byte. The fix reduces the width of each DMA read to the RX FIFO to a single byte, mitigating data loss. Publi...

SUSE 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...
