  "details": "In the Linux kernel, the following vulnerability has been resolved:  RDMA/ionic: bound node_desc sysfs read with %.64s  node_desc[64] in struct ib_device 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 node_desc_store() performs a raw memcpy of up to IB_DEVICE_NODE_DESC_MAX bytes with no NUL termination:    memcpy(desc.node_desc, buf, min_t(int, count, IB_DEVICE_NODE_DESC_MAX));  If exactly 64 bytes are written via the node_desc sysfs file, the array contains no NUL byte. The ionic hca_type_show() handler uses unbounded \"%s\" and will read past the end of node_desc into adjacent fields of struct ib_device until it encounters a NUL.  ionic supports IB_DEVICE_MODIFY_NODE_DESC, so this is triggerable by userspace.  Match the core handler and bound the format specifier.",
