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

Description An issue exists in the Linux kernel’s regulator core that can lead to an integer underflow. This occurs when a non-integer ratio is used between delay and poll enabled time, causing time remaining to underflow and preventing the loop from exiting as expected. The delay value can originate from Device Tree (DT) data, while poll enabled time is defined within the driver, making this scenario possible.

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