Description OSIDB Bzimport 2026-08-15 06:34:05 UTC 
In the Linux kernel, the following vulnerability has been resolved:

spi: atcspi200: fix use-after-free when driver unbind

DMA resource is initialized after SPI controller registration. So
when driver unbind, this can trigger a use-after-free when DMA is
torn down while the controller is still alive and triggers DMA transfers.
