CVE-2024-40986

CVE-2024-40986 affects the Linux kernel DMA engine for Xilinx XDMA. The issue arises from data synchronization in xdma_channel_isr() where the code does not properly sequence operations before using xdma->stop_request, requiring the vchan lock prior to stop_request usage. The vulnerability is ...

CVE-2024-40956

CVE-2024-40956 affects the Linux kernel (dmaengine: idxd). The vulnerability is a use-after-free in irq_process_work_list, caused by reusing a descriptor while it may still be referenced. The fix uses list_for_each_entry_safe() to safely iterate and delete entries during the loop; freeing the des...
