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.
