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-2026-45864 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-2026-45864/ (Markdown: https://insights.sbomify.com/CVE-2026-45864/index.md)","id":"CVE-2026-45864","markdown":"https://insights.sbomify.com/CVE-2026-45864/index.md","name":"CVE-2026-45864","record":{"aliases":["BELL-CVE-2026-45864","DEBIAN-CVE-2026-45864","GHSA-g925-qgm3-hc5p","ROOT-OS-UBUNTU-2204-CVE-2026-45864","ROOT-OS-UBUNTU-2404-CVE-2026-45864","UBUNTU-CVE-2026-45864"],"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":"low_privilege","summary":"A flaw in the Linux kernel's NTFS3 driver allows attackers to cause a denial of service via an infinite loop triggered by invalid data processing.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-835","name":"Loop with Unreachable Exit Condition"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nfs/ntfs3: prevent infinite loops caused by the next valid being the same\n\nWhen processing valid within the range [valid : pos), if valid cannot\nbe retrieved correctly, for example, if the retrieved valid value is\nalways the same, this can trigger a potential infinite loop, similar\nto the hung problem reported by syzbot [1].\n\nAdding a check for the valid value within the loop body, and terminating\nthe loop and returning -EINVAL if the value is the same as the current\nvalue, can prevent this.\n\n[1]\nINFO: task syz.4.21:6056 blocked for more than 143 seconds.\nCall Trace:\n rwbase_write_lock+0x14f/0x750 kernel/locking/rwbase_rt.c:244\n inode_lock include/linux/fs.h:1027 [inline]\n ntfs_file_write_iter+0xe6/0x870 fs/ntfs3/file.c:1284","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"fs/ntfs3: prevent infinite loops caused by the next valid being the same","id":"CVE-2026-45864","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":7,"next":{"headline":"mctp i2c: initialise event handler read bytes","id":"CVE-2026-45865"},"packages":[],"prev":{"headline":"i3c: dw: Fix memory leak in dw_i3c_master_i2c_xfers()","id":"CVE-2026-45863"},"products":["Linux"],"published":"2026-05-27","related":[{"cvss_score":8.8,"headline":"Linux Kernel Out-of-Bounds Write","id":"CVE-2026-53266","kev_date_added":"2026-09-18","published":"2026-06-25"},{"cvss_score":8.8,"headline":"Linux Kernel Improper Input Validation","id":"CVE-2013-6282","kev_date_added":"2022-09-15","published":"2013-11-19"},{"cvss_score":8.4,"headline":"Linux Kernel Heap-Based Buffer Overflow","id":"CVE-2022-0185","kev_date_added":"2024-08-21","published":"2022-02-11"},{"cvss_score":8.4,"headline":"Linux Kernel Privilege Escalation","id":"CVE-2013-2094","kev_date_added":"2022-09-15","published":"2013-05-14"},{"cvss_score":7.8,"headline":"Linux Kernel Unspecified","id":"CVE-2026-53362","kev_date_added":"2026-08-27","published":"2026-07-04"},{"cvss_score":7.8,"headline":"Linux Kernel Missing Initialization of a Variable","id":"CVE-2026-46300","kev_date_added":"2026-10-28","published":"2026-05-23"},{"cvss_score":7.8,"headline":"Linux Kernel Race Condition","id":"CVE-2025-39964","kev_date_added":"2026-09-18","published":"2025-10-13"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-05-27","vendors":["Linux"]},"summary":"A flaw in the Linux kernel's NTFS3 driver allows attackers to cause a denial of service via an infinite loop triggered by invalid data processing.","url":"https://insights.sbomify.com/CVE-2026-45864/"}
