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-2026-92494 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-2026-92494/ (Markdown: https://insights.sbomify.com/CVE-2026-92494/index.md)","id":"CVE-2026-92494","markdown":"https://insights.sbomify.com/CVE-2026-92494/index.md","name":"CVE-2026-92494","record":{"aliases":["AZL-102540","BELL-CVE-2026-92494","DEBIAN-CVE-2026-92494","GHSA-72fx-6p3v-7c2x","UBUNTU-CVE-2026-92494"],"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 local attacker can cause a memory leak in the Linux kernel ext4 filesystem, potentially leading to denial of service.","user_interaction":"not_required","vuln_class":"memory_corruption"},"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\next4: fix buffer_head leak in ext4_init_orphan_info\n\next4_init_orphan_info() reads orphan file blocks with ext4_bread()\nand stores the returned buffer_head in oi-\u003eof_binfo[i].ob_bh.\n\nIf ext4_bread() succeeds but the orphan block magic or checksum\nvalidation fails, the function jumps to out_free.
