CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's csum_partial() function, which improperly calculates checksums on machines lacking vector facilities, potentially leading to incorrect checksum values derived from address zero. This flaw could compromise data integrity in applications relying on accurate checksum calculations. Organizations using Linux on systems without vector support should prioritize patching to mitigate potential data corruption risks.
Original NVD Description
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().
