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-2024-35825 in the wild and no public exploit code.\n\nAffected product: Debian Debian 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-2024-35825/ (Markdown: https://insights.sbomify.com/CVE-2024-35825/index.md)","id":"CVE-2024-35825","markdown":"https://insights.sbomify.com/CVE-2024-35825/index.md","name":"CVE-2024-35825","record":{"aliases":["BELL-CVE-2024-35825","DEBIAN-CVE-2024-35825","GHSA-pcfp-3pw8-73vr","UBUNTU-CVE-2024-35825"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel USB gadget","requires_auth":"low_privilege","summary":"A flaw in the Linux kernel USB NCM gadget driver causes a crash when processing zero block length packets, leading to denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"debian_linux","vendor":"debian"},{"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":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nusb: gadget: ncm: Fix handling of zero block length packets\n\nWhile connecting to a Linux host with CDC_NCM_NTB_DEF_SIZE_TX\nset to 65536, it has been observed that we receive short packets,\nwhich come at interval of 5-10 seconds sometimes and have block\nlength zero but still contain 1-2 valid datagrams present.\n\nAccording to the NCM spec:\n\n\"If wBlockLength = 0x0000, the block is terminated by a\nshort packet. In this case, the USB transfer must still\nbe shorter than dwNtbInMaxSize or dwNtbOutMaxSize. If\nexactly dwNtbInMaxSize or dwNtbOutMaxSize bytes are sent,\nand the size is a multiple of wMaxPacketSize for the\ngiven pipe, then no ZLP shall be sent.\n\nwBlockLength= 0x0000 must be used with extreme care, because\nof the possibility that the host and device may get out of\nsync, and because of test issues.\n\nwBlockLength = 0x0000 allows the sender to reduce latency by\nstarting to send a very large NTB, and then shortening it when\nthe sender discovers that there’s not sufficient data to justify\nsending a large NTB\"\n\nHowever, there is a potential issue with the current implementation,\nas it checks for the occurrence of multiple NTBs in a single\ngiveback by verifying if the leftover bytes to be processed is zero\nor not. If the block length reads zero, we would process the same\nNTB infintely because the leftover bytes is never zero and it leads\nto a crash. Fix this by bailing out if block length reads zero.","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":"usb: gadget: ncm: Fix handling of zero block length packets","id":"CVE-2024-35825","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"debian:debian_linux","products":["debian:debian_linux","linux:linux_kernel"],"type":"denial_of_service","year":"2024"},"n_packages":0,"n_references":8,"next":{"headline":"block: Fix page refcounts for unaligned buffers in __bio_release_pages()","id":"CVE-2024-35826"},"packages":[],"prev":{"headline":"misc: lis3lv02d_i2c: Fix regulators getting en-/dis-abled twice on suspend/resume","id":"CVE-2024-35824"},"products":["Linux"],"published":"2024-05-17","related":[{"cvss_score":10,"headline":"ProFTPD Improper Access Control","id":"CVE-2015-3306","kev_date_added":"2026-10-08","published":"2015-05-18"},{"cvss_score":9.9,"headline":"RoundCube Webmail Deserialization of Untrusted Data","id":"CVE-2025-49113","kev_date_added":"2026-02-20","published":"2025-06-02"},{"cvss_score":9.8,"headline":"GNU InetUtils Argument Injection","id":"CVE-2026-24061","kev_date_added":"2026-01-26","published":"2026-01-21"},{"cvss_score":9.8,"headline":"Linux Kernel Improper Check for Unusual or Exceptional Conditions","id":"CVE-2025-39682","kev_date_added":"2026-09-18","published":"2025-09-05"},{"cvss_score":9.8,"headline":"Mozilla Firefox Use-After-Free","id":"CVE-2024-9680","kev_date_added":"2024-10-15","published":"2024-10-09"},{"cvss_score":9.8,"headline":"RARLAB UnRAR Directory Traversal","id":"CVE-2022-30333","kev_date_added":"2022-08-09","published":"2022-05-09"},{"cvss_score":9.8,"headline":"Roundcube Webmail SQL Injection","id":"CVE-2021-44026","kev_date_added":"2023-06-22","published":"2021-11-19"}],"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-05-23","vendors":["Linux"]},"summary":"A flaw in the Linux kernel USB NCM gadget driver causes a crash when processing zero block length packets, leading to denial of service.","url":"https://insights.sbomify.com/CVE-2024-35825/"}
