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-2026-53132: Missing Release of Memory after Effective Lifetime

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 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,...

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...
