The issue is related to the Linux kernel's mmc core component, where a negative index can be accessed with an array. This occurs because the iterator `i` is not checked to be greater than zero before assigning `prev idata = idatas[i - 1]`. The vulnerability may allow an attacker to cause a denial of service.

A weakness has been identified in the UFS standard that could result in a security issue. This issue may exist in systems where the Host boot ROM code implements the UFS Boot feature to boot from UFS compliant storage devices. The UFS Boot feature is provided by UFS devices to support platforms that need to download the system boot loader from external non-volatile storage locations. Adversaries may disable the boot capability or revert to an old boot loader code if the host boot ROM code is improperly implemented. UFS Host Boot ROM implementers may be impacted by this issue. UFS devices are only impacted when connected to a vulnerable UFS Host and are not independently impacted by this issue.
