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

Description: The issue is related to the swiotlb component of the Linux kernel. It occurs when using restricted DMA pools in conjunction with dynamic SWIOTLB, leading to a crash at boot-time due to a NULL pointer dereference. The crash happens because the add mem pool() function tries to add to a NULL mem->pools list. The problem can be fixed by initializing the mem->pools list head in rmem swiotlb device init() before calling add mem pool().

Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.
