CVE-2026-64048 is a NULL pointer dereference vulnerability in the Linux kernel SMC networking subsystem. On an SMC-D client, device-array slot 0 is reserved for an SMC-Dv1 device, while SMC-Dv2 device entries start at index 1. When no V1 device is selected, slot 0 retains a NULL device pointer and a zero channel identifier (CHID). The smc_v2_determine_accepted_chid() function searches from index 0 and matches the peer's CHID without checking whether the corresponding device pointer is valid. A malicious peer responding to an SMC-Dv2-only proposal with an ACCEPT containing CHID 0 can therefore select the empty slot. The subsequent device-lock dereference in smc_conn_create() causes a kernel fault and denial of service.
