Description SMASH SMASH 2024-05-28 16:34:45 UTC

In the Linux kernel, the following vulnerability has been resolved:

vdpa: ifcvf: Do proper cleanup if IFCVF init fails

ifcvf_mgmt_dev leaks memory if it is not freed before
returning. Call is made to correct return statement
so memory does not leak. ifcvf_init_hw does not take
care of this so it is needed to do it here.
