Summary
In the Linux kernel, the following vulnerability has been resolved: RDMA/nldev: validate dynamic counter attribute length RDMA_NLDEV_ATTR_STAT_HWCOUNTERS is a nested attribute whose children are consumed directly with nla_get_u32(). The top-level policy validates only the container, so it does not establish the fixed shape of each child. Require every child payload to be exactly one u32 before reading it.
