Severity ?
7.1 (High) - CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: vsock/virtio: fix potential unbounded skb queue virtio_transport_inc_rx_pkt() checks vvs->rx_bytes + len > vvs->buf_alloc. virtio_transport_recv_enqueue() skips coalescing for packets with VIRTIO_VSOCK_SEQ_EOM. If fed with packets with len == 0 and VIRTIO_VSOCK_SEQ_EOM, a very large number of packets can be queued because vvs->rx_bytes stays at 0. Fix this by estimating the skb metadata size: (Number of skbs in the queue) * SKB_TRUESIZE(0)

I found no confidentiality primitive.\\nI:N - The flaw queues attacker-supplied zero-length skb metadata but does not corrupt memory or provide an arbitrary write/control-flow primitive. I found no integrity impact beyond denial of service.\\nA:H - The receive queue can grow without the intended buffer-accounting limit, causing unbounded host kernel memory consumption. A sustained flood can drive OOM or host-wide service loss.\"}]}], \"affected\": [{\"product\": \"Linux\", \"vendor\": \"Linux\", \"defaultStatus\": \"unaffected\", \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"programFiles\": [\"net/vmw_vsock/virtio_transport_common.c\"], \"versions\": [{\"version\": \"077706165717686a2a6a71405fef036cd5b37ae0\", \"lessThan\": \"1eca304f97a34ed5e921e1f0e06c8b241f25bf12\", \"status\": \"affected\", \"versionType\": \"git\"}, {\"version\": \"077706165717686a2a6a71405fef036cd5b37ae0\", \"lessThan\": \"9bdc637fde66b63d6cad0caacd034888bb7bf5f5\", \"status\": \"affected\", \"versionType\": \"git\"}, {\"version\": \"077706165717686a2a6a71405fef036cd5b37ae0\", \"lessThan\": \"100d5b2ffdc6468b9e48532641f29e83efdcb63c\", \"status\": \"affected\", \"versionType\": \"git\"}, {\"version\": \"077706165717686a2a6a71405fef036cd5b37ae0\", \"lessThan\": \"059b7dbd20a6f0c539a45ddff1573cb8946685b5\", \"status\": \"affected\", \"versionType\": \"git\"}, {\"version\": \"5852a2b573f7a3a29df46296e56aa3491e589cdf\", \"status\": \"affected\", \"versionType\": \"git\"}, {\"version\": \"6.1.63\", \"lessThan\": \"6.2\", \"status\": \"affected\", \"versionType\": \"semver\"}]}, {\"product\": \"Linux\", \"vendor\": \"Linux\", \"defaultStatus\": \"affected\", \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"programFiles\": [\"net/vmw_vsock/virtio_transport_common.c\"], \"versions\": [{\"version\": \"6.3\", \"status\": \"affected\"}, {\"version\": \"0\", \"lessThan\": \"6.3\", \"status\": \"unaffected\", \"versionType\": \"semver\"}, {\"version\": \"6.12.94\", \"lessThanOrEqual\": \"6.12.*\", \"status\": \"unaffected\", \"versionType\": \"semver\"}, {\"version\": \"6.18.36\", \"lessThanOrEqual\": \"6.18.*\", \"status\": \"unaffected\", \"versionType\": \"semver\"}, {\"version\": \"7.0.13\", \"lessThanOrEqual\": \"7.0.*\", \"status\": \"unaffected\", \"versionType\": \"semver\"}, {\"version\": \"7.1\", \"lessThanOrEqual\": \"*\", \"status\": \"unaffected\", \"versionType\": \"original_commit_for_fix\"}]}], \"cpeApplicability\": [{\"nodes\": [{\"operator\": \"OR\", \"negate\": false, \"cpeMatch\": [{\"vulnerable\": true, \"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"versionStartIncluding\": \"6.3\", \"versionEndExcluding\": \"6.12.94\"}, {\"vulnerable\": true, \"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"versionStartIncluding\": \"6.3\", \"versionEndExcluding\": \"6.18.36\"}, {\"vulnerable\": true, \"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"versionStartIncluding\": \"6.3\", \"versionEndExcluding\": \"7.0.13\"}, {\"vulnerable\": true, \"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"versionStartIncluding\": \"6.3\", \"versionEndExcluding\": \"7.1\"}, {\"vulnerable\": true, \"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"versionStartIncluding\": \"6.1.63\"}]}]}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/1eca304f97a34ed5e921e1f0e06c8b241f25bf12\"}, {\"url\": \"https://git.kernel.org/stable/c/9bdc637fde66b63d6cad0caacd034888bb7bf5f5\"}, {\"url\": \"https://git.kernel.org/stable/c/100d5b2ffdc6468b9e48532641f29e83efdcb63c\"}, {\"url\": \"https://git.kernel.org/stable/c/059b7dbd20a6f0c539a45ddff1573cb8946685b5\"}], \"title\": \"vsock/virtio: fix potential unbounded skb queue\", \"x_generator\": {\"engine\": \"bippy-1.2.0\"}}, \"adp\": [{\"metrics\": [{\"other\": {\"type\": \"ssvc\", \"content\": {\"id\": \"CVE-2026-53132\", \"role\": \"CISA Coordinator\", \"options\": [{\"Exploitation\": \"none\"}, {\"Automatable\": \"no\"}, {\"Technical Impact\": \"partial\"}], \"version\": \"2.0.3\", \"timestamp\": \"2026-10-16T15:25:50.523293Z\"}}}], \"problemTypes\": [{\"descriptions\": [{\"lang\": \"en\", \"type\": \"CWE\", \"cweId\": \"CWE-400\", \"description\": \"CWE-400 Uncontrolled Resource Consumption\"}]}], \"providerMetadata\": {\"orgId\": \"134c704f-9b21-4f2e-91b3-4a467353bcc0\", \"shortName\": \"CISA-ADP\", \"dateUpdated\": \"2026-10-16T15:25:51.179Z\"}, \"title\": \"CISA ADP Vulnrichment\"}]}",
