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-2026-74394 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-2026-74394/ (Markdown: https://insights.sbomify.com/CVE-2026-74394/index.md)","id":"CVE-2026-74394","markdown":"https://insights.sbomify.com/CVE-2026-74394/index.md","name":"CVE-2026-74394","record":{"aliases":["BELL-CVE-2026-74394","DEBIAN-CVE-2026-74394","GHSA-f87m-vg23-g294","UBUNTU-CVE-2026-74394"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel RDMA","requires_auth":"none","summary":"A malicious network initiator can trigger an integer overflow in the Linux kernel RDMA subsystem, potentially leading to memory corruption or denial of service.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/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\nRDMA/srpt: fix integer overflow in immediate data length check\n\nimm_buf-\u003elen is a user-controlled uint32_t received from the network.\nAdding it to imm_data_offset without overflow checking allows a\nmalicious initiator to send len=0xFFFFFFFF, causing req_size to wrap\naround to a small value, bypassing the bounds check, and subsequently\npassing a ~4GB length to sg_init_one().\n\nUse check_add_overflow() to detect wrapping before the comparison.","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":"RDMA/srpt: fix integer overflow in immediate data length check","id":"CVE-2026-74394","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"integer_overflow","year":"2026"},"n_packages":0,"n_references":8,"next":{"headline":"RDMA/mlx5: Fix devx subscribe-event unwind NULL dereference","id":"CVE-2026-74395"},"packages":[],"prev":{"headline":"drm/syncobj: Fix memory leak in drm_syncobj_find_fence()","id":"CVE-2026-74393"},"products":["Linux"],"published":"2026-08-15","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":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-16","vendors":["Linux"]},"summary":"A malicious network initiator can trigger an integer overflow in the Linux kernel RDMA subsystem, potentially leading to memory corruption or denial of service.","url":"https://insights.sbomify.com/CVE-2026-74394/"}
