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-2026-93801 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-2026-93801/ (Markdown: https://insights.sbomify.com/CVE-2026-93801/index.md)","id":"CVE-2026-93801","markdown":"https://insights.sbomify.com/CVE-2026-93801/index.md","name":"CVE-2026-93801","record":{"aliases":["AZL-103775","BELL-CVE-2026-93801","DEBIAN-CVE-2026-93801","GHSA-r8gf-cwvf-97c5","UBUNTU-CVE-2026-93801"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel SMB client","requires_auth":"low_privilege","summary":"An attacker could read uninitialized stack memory via the Linux kernel SMB client due to missing zero-initialization of a data structure.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/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\nsmb/client: zero-initialize stack-allocated cifs_open_info_data\n\nStack-allocated cifs_open_info_data may contain random data.\nThis can make some fields have wrong value if they are not set later.","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: zero-initialize stack-allocated cifs_open_info_data","id":"CVE-2026-93801","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2026"},"n_packages":0,"n_references":4,"next":{"headline":"wifi: rsi: validate beacon length before fixed buffer copy","id":"CVE-2026-93802"},"packages":[],"prev":{"headline":"btrfs: fix use-after-free on reloc root after error in insert_dirty_subvol()","id":"CVE-2026-93800"},"products":["Linux"],"published":"2026-09-24","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-21","vendors":["Linux"]},"summary":"An attacker could read uninitialized stack memory via the Linux kernel SMB client due to missing zero-initialization of a data structure.","url":"https://insights.sbomify.com/CVE-2026-93801/"}
