CVE-2026-72148

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]
