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-2026-93044 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-2026-93044/ (Markdown: https://insights.sbomify.com/CVE-2026-93044/index.md)","id":"CVE-2026-93044","markdown":"https://insights.sbomify.com/CVE-2026-93044/index.md","name":"CVE-2026-93044","record":{"aliases":["BELL-CVE-2026-93044","DEBIAN-CVE-2026-93044","GHSA-pp7w-23pg-4fgh","UBUNTU-CVE-2026-93044"],"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":"low_privilege","summary":"A local attacker can trigger a kernel crash by loading BPF programs with arena instructions that force an unsupported interpreter fallback.","user_interaction":"not_required","vuln_class":"denial_of_service"},"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: Disallow interpreter fallback for arena-related insns\n\nSince the interpreter does not support the arena-related insns,\ninterpreter fallback should not be allowed for these insns in\ncore.c::__bpf_prog_select_runtime().\n\nCurrently, when the interpreter executes the arena ST/LDX/STX insns,\nit would hit the BUG_ON() in ___bpf_prog_run() at run time.\n\n[    2.579196] BPF interpreter: unknown opcode a2 (imm: 0x0)\n[    2.579998] ------------[ cut here ]------------\n[    2.580652] kernel BUG at kernel/bpf/core.c:2349!\n[    2.581314] Oops: invalid opcode: 0000 [#1] SMP PTI\n\nSet jit_required as true when arena map is used in the prog to disallow\ninterpreter fallback for arena-related insns.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"bpf: Disallow interpreter fallback for arena-related insns","id":"CVE-2026-93044","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"bpf: Reject arena frees below the arena base","id":"CVE-2026-93045"},"packages":[],"prev":{"headline":"bpf: Disallow interpreter fallback for gotox insn","id":"CVE-2026-93043"},"products":["Linux"],"published":"2026-09-17","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-19","vendors":["Linux"]},"summary":"A local attacker can trigger a kernel crash by loading BPF programs with arena instructions that force an unsupported interpreter fallback.","url":"https://insights.sbomify.com/CVE-2026-93044/"}
