CVE-2026-72476
Riassunto
di MITRE • 15/08/2026
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.
Fixes it by moving dma_chan_put() after the check.
