CVE-2023-52842

CVE-2023-52842 affects the Linux kernel virtio_vsock path. The issue arises from uninitialized buf_alloc and fwd_cnt fields in struct virtio_vsock_hdr when a new skb is allocated in virtio_transport_init_hdr(), leading to a KMSAN-uninitialized-value report. The connected Astra/SUSE advisories con...
