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-2026-74358 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-2026-74358/ (Markdown: https://insights.sbomify.com/CVE-2026-74358/index.md)","id":"CVE-2026-74358","markdown":"https://insights.sbomify.com/CVE-2026-74358/index.md","name":"CVE-2026-74358","record":{"aliases":["BELL-CVE-2026-74358","DEBIAN-CVE-2026-74358","GHSA-pvr9-cffv-xgvv","UBUNTU-CVE-2026-74358"],"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 ext4 fast commit path can cause system hangs or crashes due to incorrect wait/wake bit mapping on 64-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\next4: fix fast commit wait/wake bit mapping on 64-bit\n\nOn 64-bit, ext4 dynamic inode states live in the upper half of i_flags,\nand ext4_test_inode_state() applies the corresponding +32 offset.\n\nThe fast-commit wait and wake paths open-coded the wait key with the raw\nEXT4_STATE_* value.
