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

Description A flaw exists in the Linux kernel's pinctrl subsystem, specifically within the freescale driver. The issue involves a memory out-of-bounds condition that occurs when the number of configurations (num configs) is 1. When a configuration is passed in by pad wakeup, the code attempts to fetch a configuration beyond the allocated memory, leading to a memory corruption issue detected by KASAN. The fix modifies the code to only fetch configurations when num configs is greater than 1.

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