Description OSIDB Bzimport 2026-05-01 15:02:44 UTC
In the Linux kernel, the following vulnerability has been resolved:

spi: stm32-ospi: Fix resource leak in remove() callback

The remove() callback returned early if pm_runtime_resume_and_get()
failed, skipping the cleanup of spi controller and other resources.

Remove the early return so cleanup completes regardless of PM resume
result.
