CVE-2025-71186 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. In the Linux kernel, the following vulnerability has been resolved: dmaengine: stm32: dmamux: fix device leak on route allocation Make sure to drop the reference taken when looking up the DMA mux platform device during route allocation. Note that holding a reference to a device does not prevent its driver data from going away so there is no point in keeping the reference.. EPSS estimates a 0.18% chance of exploitation in the next 30 days.
