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-2026-68286 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-2026-68286/ (Markdown: https://insights.sbomify.com/CVE-2026-68286/index.md)","id":"CVE-2026-68286","markdown":"https://insights.sbomify.com/CVE-2026-68286/index.md","name":"CVE-2026-68286","record":{"aliases":["AZL-95229","BELL-CVE-2026-68286","DEBIAN-CVE-2026-68286","GHSA-xcpv-vj7m-3hh9","UBUNTU-CVE-2026-68286"],"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":"none","summary":"A race condition in the Linux kernel drop_monitor allows local attackers to corrupt statistics or cause denial of service on 32-bit systems.","user_interaction":"not_required","vuln_class":"race_condition"},"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\ndrop_monitor: perform u64_stats updates under IRQ-disabled section\n\nIn net_dm_packet_trace_kfree_skb_hit() and net_dm_hw_trap_packet_probe(),\nu64_stats_update_begin() / u64_stats_inc() / u64_stats_update_end() were\ncalled after spin_unlock_irqrestore(\u0026...drop_queue.lock, flags), when local\nIRQs had already been re-enabled.\n\nTracepoint probes can execute in IRQ or softirq context.
