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

Description The issue concerns potential integer multiplication overflow errors in the RDMA/hfi1 component of the Linux kernel. Specifically, when multiplying different types, an overflow can occur even when storing the result in a larger type, due to the conversion being done after the multiplication. This can lead to arithmetic overflow and an incorrect value. The problem is corrected in the inter packet delay calculation by ensuring one of the operands is u64, which promotes the other to u64 as well, preventing overflow.

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