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. (NVD)
