Summary
In the Linux kernel, the following vulnerability has been resolved: dmaengine: dw-edma: Add spinlock to protect DONE_INT_MASK and ABORT_INT_MASK The DONE_INT_MASK and ABORT_INT_MASK registers are shared by all DMA channels, and modifying them requires a read-modify-write sequence. Because this operation is not atomic, concurrent calls to dw_edma_v0_core_start() can introduce race conditions if two channels update these registers simultaneously. Add a spinlock to serialize access to these registers and prevent race conditions. [den: update dw_edma.lock comment]
