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", "affected": [ { "package": { "ecosystem": "Raspberry Pi OS:12", "name": "linux" }, "versions": [ "1:6.1.21-1+rpt1", "1:6.1.47-1+rpt2", "1:6.1.47-1+rpt4", "1:6.1.54-1+rpt2",
