Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The mmc add host() function may return an error, and if this return value is ignored, memory allocated in mmc alloc host() can be leaked. This memory leak can lead to a kernel crash during device removal due to attempting to delete a device that was not properly added. The fix involves checking the return value of mmc add host() and, in case of an error, calling mmc free host() and free irq().
