CVE-2022-50023 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. In the Linux kernel, the following vulnerability has been resolved: dmaengine: dw-axi-dmac: ignore interrupt if no descriptor If the channel has no descriptor and the interrupt is raised then the kernel will OOPS. Check the result of vchan_next_desc() in the handler axi_chan_block_xfer_complete() to avoid the error happening.. EPSS estimates a 0.15% chance of exploitation in the next 30 days.
