Description

In the Linux kernel, the following vulnerability has been resolved: mmc: sdhci-esdhc-imx: use pm_runtime_resume_and_get() in suspend Replace pm_runtime_get_sync() with pm_runtime_resume_and_get() to simplify error handling. pm_runtime_resume_and_get() automatically drops the usage counter on failure, avoiding the need for a separate pm_runtime_put_noidle() call. If it fails, the device is unclocked and accessing hardware registers would cause a kernel panic, so return the error immediately.

Affected products

• Linux kernel: 6.16 — fixed in 7.2

How to fix

Upgrade to a fixed version: Linux kernel 7.2. Check the vendor advisory for mitigations.
