It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-98317 in the wild and no public exploit code.\n\nAffected product: Linux. 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-2026-98317/ (Markdown: https://insights.sbomify.com/CVE-2026-98317/index.md)","id":"CVE-2026-98317","markdown":"https://insights.sbomify.com/CVE-2026-98317/index.md","name":"CVE-2026-98317","record":{"aliases":["AZL-106332","BELL-CVE-2026-98317","DEBIAN-CVE-2026-98317","GHSA-52cr-c2c7-9x84","UBUNTU-CVE-2026-98317"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"high_privilege","summary":"A local attacker with high privileges can cause a denial of service in the Linux kernel by exploiting an integer overflow in neighbor table probe time settings.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","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\nneighbour: Enforce min/max to NDTPA_INTERVAL_PROBE_TIME_MS.\n\nNDTPA_INTERVAL_PROBE_TIME_MS sets .type and .min but misses\n.validation_type, so no validation is applied:\n\n  # ynl --family rt-neigh --do setneightbl \\\n  --json '{\"name\": \"arp_cache\", \"parms\": {\"interval-probe-time-ms\": 0}}'\n\n  # ynl --family rt-neigh --dump getneightbl --output-json | \\\n  jq '.[] | select(.name == \"arp_cache\" and has(\"config\"))\n          | .parms[\"interval-probe-time-ms\"]'\n  0\n\nMoreover, nla_get_msecs() uses msecs_to_jiffies(), and u64 is\nsilently cast to u32, so a larger value can bypass the min check:\n\n  e.g. 4294967296 == 0x100000000\n\n  # ynl --family rt-neigh --do setneightbl \\\n  --json '{\"name\": \"arp_cache\", \"parms\": {\"interval-probe-time-ms\": 4294967296}}'\n\n  # ynl --family rt-neigh --dump getneightbl --output-json | \\\n  jq '.[] | select(.name == \"arp_cache\" and has(\"config\"))\n          | .parms[\"interval-probe-time-ms\"]'\n  0\n\nmsecs_to_jiffies() returns MAX_JIFFY_OFFSET if the value is\nlarger than INT_MAX.
