CVE-2026-72476Source published Source updated
In the Linux kernel, the following vulnerability has been resolved: dmaengine: Fix possible use after free In dma_release_channel(), check chan->device->privatecnt after call dma_chan_put(). However, dma_chan_put() call dma_device_put() which could release the last reference of the device if the DMA provider is already gone and hence free it.
