In the Linux kernel, the following vulnerability has been resolved:

s390/checksum: Fix csum_partial() without vector facility

Currently csum_partial() calls csum_copy() with copy=false and dst=NULL.

On machines without the vector facility, csum_copy() falls back to

cksm(dst, ...), causing the checksum to be calculated from address zero

instead of the source buffer.

The VX implementation already checksums data loaded from src. Make the

fallback do the same by passing src to cksm(). (NVD)
