CVE-2026-89506

CVE-2026-89506 affects the Linux kernel RDMA/uverbs subsystem. The root cause is a missing UVERBS_ATTR_UHW attribute in the UVERBS_METHOD_REG_MR ioctl definition. Three drivers—mthca , irdma , and siw —associate UHW data with reg_mr but assume the udata pointer is non-NULL. Because the attribute ...
