  "description": "In the Linux kernel, the following vulnerability has been resolved:  s390/vfio_ccw: Free all memory if cp_init() fails  The routine cp_free() is called to unpin/free any memory once an I/O is completed successfully, or if cp_prefetch() fails. But if cp_init() fails, and cp-\u003Einitialized is not enabled, the same routine cannot be used to free all the memory.  An attempt to address this exists in ccwchain_handle_ccw(), where a single call to ccwchain_free() is made for the currently-processed CCW segment. But this will leak other segments (created as a result of a Transfer in Channel) that had been allocated as part of the same channel program.  Address this by performing the cleanup outside of the recursive ccwchain_handle_ccw()/ccwchain_loop_tic() logic.",
