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

Description An array-index-out-of-bounds issue exists in the mtd intel dg.c file. The regions array is accessed before the nregions variable is set, which determines the array count. Additionally, the loop silently ignores ENOMEM (out of memory errors) and continues setting other entries.

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