In the Linux kernel, the following vulnerability has been resolved:
dmaengine: xilinx_dma: Fix channel idle state management in AXIDMA and MCDMA interrupt handlers
Fix a race condition in AXIDMA and MCDMA irq handlers where the channel could be incorrectly marked as idle and attempt spurious transfers when descriptors are still being processed.
The issue occurs when:
Only mark the channel as idle and start new transfers when the active list is actually empty, ensuring proper channel state management and avoiding spurious transfer attempts.
