Detail

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

openvswitch: fix memory leak at failed datapath creation

ovs_dp_cmd_new()->ovs_dp_change()->ovs_dp_set_upcall_portids() allocates array via kmalloc. If for some reason new_vport() fails during ovs_dp_cmd_new() dp->upcall_portids must be freed. Add missing kfree.

Kmemleak example: unreferenced object 0xffff88800c382500 (size 64):
comm "dump_state", pid 323, jiffies 4294955418 (age 104.347s)
