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-2026-90333 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-2026-90333/ (Markdown: https://insights.sbomify.com/CVE-2026-90333/index.md)","id":"CVE-2026-90333","markdown":"https://insights.sbomify.com/CVE-2026-90333/index.md","name":"CVE-2026-90333","record":{"aliases":["AZL-102681","BELL-CVE-2026-90333","DEBIAN-CVE-2026-90333","GHSA-62c9-4g59-6rj6","UBUNTU-CVE-2026-90333"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Linux kernel dm-integrity","requires_auth":"high_privilege","summary":"An attacker with raw write access can bypass integrity checks by forging discard markers, requiring local access and specific configuration.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"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\ndm-integrity: replace forgeable discard filler with a keyed sector marker\n\nThe discard-block check in dm_integrity_rw_tag() treats a stored tag\nof all 0xf6 bytes (DISCARD_FILLER) as proof a block was discarded and\nskips HMAC verification. allow_discards is only accepted in\ndm-integrity's standalone mode.
