CVE-2026-74265

Description

A flaw was found in the mana network driver of the Linux kernel. When creating a General DMA (GDMA) queue, the queue->id may not be properly initialized. If the queue creation fails before a valid ID is assigned, a subsequent cleanup operation can incorrectly use a zero ID, potentially corrupting the Completion Queue (CQ) table. This could lead to system instability or a denial of service.
