CVE-2026-53132

A flaw was found in the Linux kernel's vsock/virtio component. A remote attacker could send specially crafted packets with zero length and an End-of-Message EOM flag. This could lead to an unbounded queue of packets, consuming excessive memory and potentially causing a Denial of Service DoS due t...

CVE-2026-52994

A flaw was found in the Linux kernel's vsock/virtio component. This vulnerability involves an accounting error in the MSGZEROCOPY pinned-pages mechanism, where the system's resource limit for locked memory RLIMITMEMLOCK may not be properly enforced. This could allow a local attacker or a maliciou...

CVE-2026-53132

CVE-2026-53132 affects the Linux kernel vsock/virtio, where receiving zero-length packets with VIRTIO_VSOCK_SEQ_EOM could cause an unbounded skb queue growth, exhausting memory. The root cause is a miscalculation of backlog: vvs->rx_bytes + len > vvs->buf_alloc allows large queues when l...

CVE-2026-52994

CVE-2026-52994 affects the Linux kernel virtio transport for vsock zcopy: virtio_transport_init_zcopy_skb() previously used iter->count as the size for msg_zerocopy_realloc(), which then desks mm_account_pinned_pages() for RLIMIT_MEMLOCK. Because iter->count is consumed by virtio_transport_...

CVE-2026-46214

A flaw was found in the Linux kernel's vsock/virtio component. This vulnerability occurs when virtiotransportrecvlisten calls skacceptqadded before transport validation, leading to a permanent increment of the skackbacklog counter if transport assignment fails. A remote attacker could exploit thi...
