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

Description The issue arises on an old x86 system with SRAT covering space above 4Gb, where the NUMA configuration is no longer refused by a CONFIG NUMA=y kernel. This is due to memblock validate numa coverage() checking for NUMA NO NODE only, leading to memblock alloc range nid()'s warning about MAX NUMNODES triggering, followed by a NULL deref in memmap init() when trying to access node 64's node data. The change makes memblock set node() warn on and adjust a passed in value of MAX NUMNODES.

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