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

Description A vulnerability in the Linux kernel has been resolved, specifically an integer overflow in the ghes estatus pool init() function. The issue occurs when calculating len during the execution of the statement len += (num ghes * GHES ESOURCE PREALLOC MAX SIZE), where both multiplication operands are signed integers. This causes a subsequent vmalloc() call to fail. The vulnerability results in a vmalloc error with a size that exceeds the total number of pages.

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