MediumCVSS 5.5/10Last modified Oct 15, 2026

Description

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.
