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

Description: A NULL pointer dereference issue in the Linux kernel has been resolved. The issue occurred because the igen6 edac driver checked all memory controllers, including a disabled one, resulting in a kernel panic. The error was identified by a kernel log indicating an expected 2 mcs, but only 1 detected, and a BUG report for an unable to handle page fault. The issue is related to the igen6 edac driver and functions such as ecclog handler(), igen6 probe(), and igen6 init().

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