  "details": "In the Linux kernel, the following vulnerability has been resolved:  dibs: loopback: validate offset and size in move_data()  The loopback move_data() performs a memcpy into the registered DMB without checking whether offset + size exceeds the DMB length.  Unlike real ISM hardware, which enforces memory region bounds natively, the software loopback has no such protection.  A peer-supplied out-of-bounds offset or oversized write would result in an OOB write past the allocated kernel buffer.  Add an explicit bounds check before the memcpy to reject such requests with -EINVAL.",
