Описание
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.
A flaw was found in the Linux kernel, specifically within the mmc: sdhci-esdhc-imx component responsible for managing multimedia card (MMC) host controllers. During system suspend operations, an error in power management could cause the system to attempt accessing hardware that is not properly initialized. This improper access would lead to a kernel panic, effectively causing the system to crash and resulting in a denial of service.
