CVE-2026-53371 RDMA/ionic: bound node_desc sysfs read with %.64s

In the Linux kernel, the following vulnerability has been resolved: RDMA/ionic: bound nodedesc sysfs read with %.64s nodedesc64 in struct ibdevice is not guaranteed to be NUL- terminated. The core IB sysfs handler uses "%.64s" for exactly this reason drivers/infiniband/core/sysfs.c:1307, since...

CVE-2026-53371

The CVE-2026-53371 issue affects the Linux kernel RDMA/ionic driver. It stems from node_desc not guaranteed to be NUL-terminated when 64 bytes are written to the node_desc sysfs file; the ionic hca_type_show() uses an unbounded %s, reading past node_desc into adjacent ib_device fields. The kernel...
