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-2026-93257 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-2026-93257/ (Markdown: https://insights.sbomify.com/CVE-2026-93257/index.md)","id":"CVE-2026-93257","markdown":"https://insights.sbomify.com/CVE-2026-93257/index.md","name":"CVE-2026-93257","record":{"aliases":["DEBIAN-CVE-2026-93257","GHSA-4jwc-f9v9-q77h","UBUNTU-CVE-2026-93257"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Linux kernel","requires_auth":"none","summary":"A flaw in the Linux kernel's block layer integrity handling can cause crashes when processing non-PI metadata, leading to denial of service.","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\nblock: handle nogenerate/noverify properly in fs-integrity\n\nCheck the BIP_CHECK flags before generating or verifying PI information,\notherwise this can be incorrectly called for non-PI metadata and\ncause generation of incorrect metadata and crashed in the verification\nhandler.\n\nThe new behavior matches that of the block layer auto-generated\nmetadata.","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":"block: handle nogenerate/noverify properly in fs-integrity","id":"CVE-2026-93257","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":"ocfs2: do not use make_bad_inode() in ocfs2_read_inode_block_full()","id":"CVE-2026-93258"},"packages":[],"prev":{"headline":"arm64: hibernate: mask DAIF before restoring hibernated kernel","id":"CVE-2026-93256"},"products":["Linux"],"published":"2026-09-24","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 flaw in the Linux kernel's block layer integrity handling can cause crashes when processing non-PI metadata, leading to denial of service.","url":"https://insights.sbomify.com/CVE-2026-93257/"}
