In the Linux kernel, the following vulnerability has been resolved:
nvmet: fix freeing unallocated p2pmem
In case p2p device was found but the p2p pool is empty, the nvme target
is still trying to free the sgl from the p2p pool instead of the
regular sgl pool and causing a crash (BUG() is called). Instead, assign
the p2p_dev for the request only if it was allocated from p2p pool.
This is the crash that was caused:
