"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nvhost/vsock: always initialize seqpacket_allow\n\nThere are two issues around seqpacket_allow:\n1. seqpacket_allow is not initialized when socket is\n created. Thus if features are never set, it will be\n read uninitialized.\n2. if VIRTIO_VSOCK_F_SEQPACKET is set and then cleared,\n then seqpacket_allow will not be cleared appropriately\n (existing apps I know about don't usually do this but\n it's legal and there's no way to be sure no one relies\n on this).\n\nTo fix:\n\t- initialize seqpacket_allow after allocation\n\t- set it unconditionally in set_features"
