subtraction underflow) deterministically force expect negative so drbd_recv_all_warn() receives SIZE_MAX bytes whenever the victim issues a remote read.\nPR:N - No account, capability, or administrative access on the victim host is required; a malicious DRBD peer or network man-in-the-middle on the replication link can send the crafted reply after connection setup, and cram-hmac-alg peer authentication is optional.\nUI:N - No end-user action is needed because diskless-primary and read-balancing configurations automatically send P_DATA_REQUEST packets to the peer, and the malicious P_DATA_REPLY is processed in the kernel receiver thread during normal I/O.\nS:U - The out-of-bounds socket receive corrupts kernel memory on the same host that runs DRBD; successful exploitation yields kernel compromise on that node but does not by itself cross a VM, container, or IOMMU security boundary.\nC:H - Receiving up to SIZE_MAX attacker-controlled bytes past the mapped

attacker-chosen network data beyond the allocated bio buffer boundary, providing a kernel out-of-bounds write primitive that can corrupt kernel structures and enable arbitrary code execution or
