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-2026-53195 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-2026-53195/ (Markdown: https://insights.sbomify.com/CVE-2026-53195/index.md)","id":"CVE-2026-53195","markdown":"https://insights.sbomify.com/CVE-2026-53195/index.md","name":"CVE-2026-53195","record":{"aliases":["BELL-CVE-2026-53195","DEBIAN-CVE-2026-53195","GHSA-397c-7vfx-vg4x","ROOT-OS-DEBIAN-11-CVE-2026-53195","ROOT-OS-DEBIAN-12-CVE-2026-53195","ROOT-OS-UBUNTU-2204-CVE-2026-53195","ROOT-OS-UBUNTU-2404-CVE-2026-53195","UBUNTU-CVE-2026-53195"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel USB driver","requires_auth":"low_privilege","summary":"A heap overflow in the Linux kernel's io_ti USB serial driver allows attackers to execute arbitrary code or escalate privileges via a malicious firmware image.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nUSB: serial: io_ti: fix heap overflow in build_i2c_fw_hdr()\n\nbuild_i2c_fw_hdr() allocates a fixed-size buffer of\n(16*1024 - 512) + sizeof(struct ti_i2c_firmware_rec) bytes, then\ncopies le16_to_cpu(img_header-\u003eLength) bytes into it without\nvalidating that Length fits within the available space after the\nfirmware record header.\n\nimg_header-\u003eLength is a __le16 from the firmware file and can be\nup to 65535. check_fw_sanity() validates the total firmware size\nbut not img_header-\u003eLength specifically.\n\nFix by rejecting images where img_header-\u003eLength exceeds the\navailable destination space.","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: serial: io_ti: fix heap overflow in build_i2c_fw_hdr()","id":"CVE-2026-53195","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":8,"next":{"headline":"USB: serial: io_ti: fix heap overflow in get_manuf_info()","id":"CVE-2026-53196"},"packages":[],"prev":{"headline":"USB: serial: kl5kusb105: fix bulk-out buffer overflow","id":"CVE-2026-53194"},"products":["Linux"],"published":"2026-06-25","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":"2026-06-25","vendors":["Linux"]},"summary":"A heap overflow in the Linux kernel's io_ti USB serial driver allows attackers to execute arbitrary code or escalate privileges via a malicious firmware image.","url":"https://insights.sbomify.com/CVE-2026-53195/"}
