Description
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.
