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-2026-74495 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-2026-74495/ (Markdown: https://insights.sbomify.com/CVE-2026-74495/index.md)","id":"CVE-2026-74495","markdown":"https://insights.sbomify.com/CVE-2026-74495/index.md","name":"CVE-2026-74495","record":{"aliases":["AZL-96299","BELL-CVE-2026-74495","DEBIAN-CVE-2026-74495","GHSA-7vcq-2p5f-22mh","UBUNTU-CVE-2026-74495"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"none","summary":"A memory leak in the igbvf driver's TX DMA error handling can lead to resource exhaustion and denial of service.","user_interaction":"not_required","vuln_class":"memory_corruption"},"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\nigbvf: Fix leak in TX DMA error cleanup\n\nIf an error is encountered while mapping TX buffers, the driver should\nunmap any buffers already mapped for that skb.\n\nBecause count is incremented before each frag mapping, it will always\nmatch the correct number of unmappings needed when dma_error is reached.\nDecrementing count before the while loop in dma_error causes an\noff-by-one error.
