CVSS 7.800000190734863 HIGH
A flaw was found in the Linux kernel's Remote Direct Memory Access (RDMA) subsystem. A divide-by-zero error can occur within the Dynamic Interrupt Moderation (DIM) mechanism when comparing statistics that evaluate to a zero value. A local attacker can trigger this issue during network operations to crash the system, resulting in a Denial of Service (DoS).
