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-2023-54063 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-2023-54063/ (Markdown: https://insights.sbomify.com/CVE-2023-54063/index.md)","id":"CVE-2023-54063","markdown":"https://insights.sbomify.com/CVE-2023-54063/index.md","name":"CVE-2023-54063","record":{"aliases":["BELL-CVE-2023-54063","DEBIAN-CVE-2023-54063","GHSA-85ww-wm3w-c8w6","UBUNTU-CVE-2023-54063"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service","data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"An out-of-bounds read in the Linux kernel NTFS3 driver allows attackers to cause a denial of service or read sensitive memory.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nfs/ntfs3: Fix OOB read in indx_insert_into_buffer\n\nSyzbot reported a OOB read bug:\n\nBUG: KASAN: slab-out-of-bounds in indx_insert_into_buffer+0xaa3/0x13b0\nfs/ntfs3/index.c:1755\nRead of size 17168 at addr ffff8880255e06c0 by task syz-executor308/3630\n\nCall Trace:\n \u003cTASK\u003e\n memmove+0x25/0x60 mm/kasan/shadow.c:54\n indx_insert_into_buffer+0xaa3/0x13b0 fs/ntfs3/index.c:1755\n indx_insert_entry+0x446/0x6b0 fs/ntfs3/index.c:1863\n ntfs_create_inode+0x1d3f/0x35c0 fs/ntfs3/inode.c:1548\n ntfs_create+0x3e/0x60 fs/ntfs3/namei.c:100\n lookup_open fs/namei.c:3413 [inline]\n\nIf the member struct INDEX_BUFFER *index of struct indx_node is\nincorrect, that is, the value of __le32 used is greater than the value\nof __le32 total in struct INDEX_HDR.
