Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-74335 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-2026-74335/ (Markdown: https://insights.sbomify.com/CVE-2026-74335/index.md)","id":"CVE-2026-74335","markdown":"https://insights.sbomify.com/CVE-2026-74335/index.md","name":"CVE-2026-74335","record":{"aliases":["BELL-CVE-2026-74335","DEBIAN-CVE-2026-74335","GHSA-qq73-h7qm-vf49","UBUNTU-CVE-2026-74335"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A local attacker can trigger a kernel crash via a race condition in BPF cgroup_skb programs, causing denial of service.","user_interaction":"not_required","vuln_class":"null_dereference"},"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\nbpf: Fix NULL pointer dereference in bpf_task_from_vpid()\n\nbpf_task_from_vpid() looks up a task in the pid namespace of the\ncurrent task, via find_task_by_vpid():\n\n  find_task_by_vpid(vpid)\n    find_task_by_pid_ns(vpid, task_active_pid_ns(current))\n      find_pid_ns(nr, ns) -\u003e idr_find(\u0026ns-\u003eidr, nr)\n\ncgroup_skb programs run in softirq, which may interrupt a task that is\nitself in do_exit().
