In the Linux kernel, the following vulnerability has been resolved:
mm: vmalloc: check if a hash-index is in cpupossiblemask
The problem is that there are systems where cpupossiblemask has gaps between set CPUs, for example SPARC. In this scenario addrtovbxa() hash function can return an index which accesses to not-possible and not setup CPU area using percpu() macro. This results in an oops on SPARC.
A per-cpu vmapblockqueue is also used as hash table, incorrectly assuming the cpupossiblemask has no gaps. Fix it by adjusting an index to a next possible CPU.
