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-2026-74545 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-2026-74545/ (Markdown: https://insights.sbomify.com/CVE-2026-74545/index.md)","id":"CVE-2026-74545","markdown":"https://insights.sbomify.com/CVE-2026-74545/index.md","name":"CVE-2026-74545","record":{"aliases":["BELL-CVE-2026-74545","DEBIAN-CVE-2026-74545","GHSA-v487-w46v-372v","UBUNTU-CVE-2026-74545"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"none","summary":"A double free vulnerability in the Linux kernel rtase driver allows attackers to cause denial of service or potentially execute code via crafted network packets.","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\nrtase: fix double free of multi-frag skb on DMA map failure\n\nIn rtase_start_xmit(), when the head buffer DMA mapping fails after\nrtase_xmit_frags() has mapped all fragments, the error path clears\nthe fragment descriptors with rtase_tx_clear_range(), which frees\nthe skb through the last-frag slot and accounts tx_dropped.
