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-2023-53194 in the wild and no public exploit code.\n\nAffected product: Linux kernel. 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-2023-53194/ (Markdown: https://insights.sbomify.com/CVE-2023-53194/index.md)","id":"CVE-2023-53194","markdown":"https://insights.sbomify.com/CVE-2023-53194/index.md","name":"CVE-2023-53194","record":{"aliases":["BELL-CVE-2023-53194","DEBIAN-CVE-2023-53194","GHSA-c2fc-xc59-v4h9","UBUNTU-CVE-2023-53194"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"A use-after-free vulnerability in the Linux kernel's NTFS3 driver allows attackers to cause a denial of service or potentially execute code via a crafted filesystem image.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":8.4,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nfs/ntfs3: Add length check in indx_get_root\n\nThis adds a length check to guarantee the retrieved index root is legit.\n\n[  162.459513] BUG: KASAN: use-after-free in hdr_find_e.isra.0+0x10c/0x320\n[  162.460176] Read of size 2 at addr ffff8880037bca99 by task mount/243\n[  162.460851]\n[  162.461252] CPU: 0 PID: 243 Comm: mount Not tainted 6.0.0-rc7 #42\n[  162.461744] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.14.0-0-g155821a1990b-prebuilt.qemu.org 04/01/2014\n[  162.462609] Call Trace:\n[  162.462954]  \u003cTASK\u003e\n[  162.463276]  dump_stack_lvl+0x49/0x63\n[  162.463822]  print_report.cold+0xf5/0x689\n[  162.464608]  ?
