An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-52967 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-2026-52967/ (Markdown: https://insights.sbomify.com/CVE-2026-52967/index.md)","id":"CVE-2026-52967","markdown":"https://insights.sbomify.com/CVE-2026-52967/index.md","name":"CVE-2026-52967","record":{"aliases":["BELL-CVE-2026-52967","DEBIAN-CVE-2026-52967","GHSA-3jxr-5523-52vg","ROOT-OS-DEBIAN-12-CVE-2026-52967","ROOT-OS-UBUNTU-2404-CVE-2026-52967","UBUNTU-CVE-2026-52967"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel SMB client","requires_auth":"none","summary":"An integer overflow in the Linux kernel SMB client allows attackers to cause infinite loops or out-of-bounds reads on 32-bit systems.","user_interaction":"required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"},{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nsmb/client: fix possible infinite loop and oob read in symlink_data()\n\nOn 32-bit architectures, the infinite loop is as follows:\n\n  len = p-\u003eErrorDataLength == 0xfffffff8\n  u8 *next = p-\u003eErrorContextData + len\n  next == p\n\nOn 32-bit architectures, the out-of-bounds read is as follows:\n\n  len = p-\u003eErrorDataLength == 0xfffffff0\n  u8 *next = p-\u003eErrorContextData + len\n  next == (u8 *)p - 8","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":"smb/client: fix possible infinite loop and oob read in symlink_data()","id":"CVE-2026-52967","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"integer_overflow","year":"2026"},"n_packages":0,"n_references":6,"next":{"headline":"KVM: s390: pci: fix GAIT table indexing due to double-scaling pointer arithmetic","id":"CVE-2026-52968"},"packages":[],"prev":{"headline":"drm: Replace old pointer to new idr","id":"CVE-2026-52966"},"products":["Linux"],"published":"2026-06-24","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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-19","vendors":["Linux"]},"summary":"An integer overflow in the Linux kernel SMB client allows attackers to cause infinite loops or out-of-bounds reads on 32-bit systems.","url":"https://insights.sbomify.com/CVE-2026-52967/"}
