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-2026-74346 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-2026-74346/ (Markdown: https://insights.sbomify.com/CVE-2026-74346/index.md)","id":"CVE-2026-74346","markdown":"https://insights.sbomify.com/CVE-2026-74346/index.md","name":"CVE-2026-74346","record":{"aliases":["BELL-CVE-2026-74346","DEBIAN-CVE-2026-74346","GHSA-r8xx-cvrr-fwj4","UBUNTU-CVE-2026-74346"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["data_read","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"none","summary":"An out-of-bounds read in the Linux kernel's irdma driver allows attackers to read kernel memory or cause a crash during CQ memory registration.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nRDMA/irdma: Fix OOB read during CQ MR registration\n\nSashiko pointed out an unrelated bug during a previous patch:\nhttps://sashiko.dev/#/patchset/20260512183852.614045-1-jmoroni%40google.com\n\nThis change fixes the bug by eliminating the cqmr-\u003esplit field which\nwas not being set properly and instead just checks the CQ resize\nfeature flag directly.\n\nThe cqmr-\u003esplit field essentially tracks whether IRDMA_FEATURE_CQ_RESIZE\nis set, but it was not being set until CQ creation time, which is _after_\nCQ memory registration (the only other place where it is referenced).\n\nAs a result, it would always be false during MR registration and would\ntherefore cause irdma_handle_q_mem to populate cqmr-\u003eshadow even for GEN_2\nHW and beyond:\n\n    cqmr-\u003eshadow = (dma_addr_t)arr[req-\u003ecq_pages];\n\nThe issue is that for GEN_2 and beyond, req-\u003ecq_pages may be exactly equal\nto iwmr-\u003epage_cnt and therefore equal to the size of arr, which would cause\nan OOB read by one.","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/irdma: Fix OOB read during CQ MR registration","id":"CVE-2026-74346","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":7,"next":{"headline":"netfilter: cttimeout: detach dataplane timeout policy and repurpose refcount","id":"CVE-2026-74347"},"packages":[],"prev":{"headline":"RDMA/siw: Fix endpoint/socket association handling","id":"CVE-2026-74345"},"products":["Linux"],"published":"2026-08-15","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-08-17","vendors":["Linux"]},"summary":"An out-of-bounds read in the Linux kernel's irdma driver allows attackers to read kernel memory or cause a crash during CQ memory registration.","url":"https://insights.sbomify.com/CVE-2026-74346/"}
