An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-90141 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-2026-90141/ (Markdown: https://insights.sbomify.com/CVE-2026-90141/index.md)","id":"CVE-2026-90141","markdown":"https://insights.sbomify.com/CVE-2026-90141/index.md","name":"CVE-2026-90141","record":{"aliases":["AZL-102327","BELL-CVE-2026-90141","DEBIAN-CVE-2026-90141","GHSA-hcq4-7chf-c998","UBUNTU-CVE-2026-90141"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["other"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel IPVS","requires_auth":"none","summary":"An integer overflow in the Linux kernel IPVS FTP helper allows attackers to truncate port or address values via crafted responses, potentially disrupting connection tracking.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":7.3,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nipvs: fix integer overflow in ftp helper port/address parsing\n\nip_vs_ftp_get_addrport() accumulates decimal digits into a __u16\n(hport) and into unsigned char (p[]) without checking for overflow.\nA crafted FTP PASV/EPSV response with an over-long port or address\noctet wraps the value, so the helper configures the data connection\nwith a truncated port/address.\n\nThe netfilter conntrack FTP helper had the same defect, fixed in\ncommit 2b413fc689ba (\"netfilter: nf_conntrack_ftp: avoid u16\noverflows\").
