EUVD-2026-45743

In the Linux kernel, the following vulnerability has been resolved: vsock/virtio: bind uarg before filling zerocopy skb virtiotransportsendpktinfo allocates or reuses the zerocopy uarg before entering the send loop, but virtiotransportallocskb still fills the skb before it inherits that uarg. Whe...

SUSE CVE-2026-53365

In the Linux kernel, the following vulnerability has been resolved: vsock/virtio: fix zerocopy completion for multi-skb sends When a large message is fragmented into multiple skbs, the zerocopy uarg is only allocated and attached to the last skb in the loop. Non-final skbs carry pinned user pages...

CVE-2026-53365

CVE-2026-53365 concerns the Linux kernel patch for vsock/virtio zerocopy completion across multi-skb sends. The fix ensures zerocopy uarg is allocated before the send loop and attached to every skb via skb_zcopy_set(), so each skb carries a reference and completion decrements correctly. This prev...

Linux Distros Unpatched Vulnerability : CVE-2026-53365

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - vsock/virtio: fix zerocopy completion for multi-skb sends When a large message is fragmented into multiple skbs, the zerocopy uarg is only allocated and attache...

Linux Distros Unpatched Vulnerability : CVE-2026-53132

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - vsock/virtio: fix potential unbounded skb queue virtiotransportincrxpkt checks vvs-rxbytes + len vvs-bufalloc. virtiotransportrecvenqueue skips coalescing for...

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...

SUSE CVE-2026-53132

In the Linux kernel, the following vulnerability has been resolved: vsock/virtio: fix potential unbounded skb queue virtiotransportincrxpkt checks vvs-rxbytes + len vvs-bufalloc. virtiotransportrecvenqueue skips coalescing for packets with VIRTIOVSOCKSEQEOM. If fed with packets with len == 0 and...

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

The CVE-2026-52994 vulnerability affects the Linux kernel’s vsock/virtio code, where the MSG_ZEROCOPY pinned-pages accounting could bypass RLIMIT_MEMLOCK on the last skb due to iter->count being consumed earlier. The fix makes pkt_len (the total bytes sent) the parameter to virtio_transport_in...

CVE-2026-52994 vsock/virtio: fix MSG_ZEROCOPY pinned-pages accounting

In the Linux kernel, the following vulnerability has been resolved: vsock/virtio: fix MSGZEROCOPY pinned-pages accounting virtiotransportinitzcopyskb uses iter-count as the size argument for msgzerocopyrealloc, which in turn passes it to mmaccountpinnedpages for RLIMITMEMLOCK accounting. However,...

Linux Distros Unpatched Vulnerability : CVE-2026-46214

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...
