An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-68312 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-2026-68312/ (Markdown: https://insights.sbomify.com/CVE-2026-68312/index.md)","id":"CVE-2026-68312","markdown":"https://insights.sbomify.com/CVE-2026-68312/index.md","name":"CVE-2026-68312","record":{"aliases":["AZL-94953","BELL-CVE-2026-68312","DEBIAN-CVE-2026-68312","GHSA-cm4r-jfcj-c3ff","UBUNTU-CVE-2026-68312"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"A memory leak in the Linux kernel CIFS module can lead to resource exhaustion and denial of service under memory pressure.","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\ncifs: fix cifsFileInfo leak on kmalloc failure in deferred close drain paths\n\nIn cifs_close_deferred_file(), cifs_close_all_deferred_files(), and\ncifs_close_deferred_file_under_dentry(), when a pending deferred close\nis cancelled via cancel_delayed_work(), the subsequent kmalloc_obj() to\nadd the file to the local processing list may fail under memory pressure.\nThe loop breaks immediately, but the cancelled work is no longer pending\n(it would have called _cifsFileInfo_put()), and the cfile is never added\nto file_head for processing.
