No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-99062/ (Markdown: https://insights.sbomify.com/CVE-2026-99062/index.md)","id":"CVE-2026-99062","markdown":"https://insights.sbomify.com/CVE-2026-99062/index.md","name":"CVE-2026-99062","record":{"aliases":["BELL-CVE-2026-99062","DEBIAN-CVE-2026-99062","GHSA-q643-38mv-p69j","UBUNTU-CVE-2026-99062"],"analysis":null,"analysis_generated_by":null,"assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nvsock/virtio: account only unread bytes in read_skb()\n\nAfter a partial stream receive, rx_bytes tracks the unread suffix while\nbuf_used and peer credit still cover the whole packet.\nvirtio_transport_read_skb() dequeues that packet but passes pkt_len for\nboth counters, underflowing rx_bytes.\n\nOn a connected CID_LOCAL stream with an SK_SKB verdict, a 40-byte read\nfrom a 100-byte packet made SIOCINQ report -40, an empty recv return\nELOOP, and poll report the empty socket readable.
