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...
