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-2024-26680 in the wild and no public exploit code.\n\nAffected product: Linux kernel. 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-2024-26680/ (Markdown: https://insights.sbomify.com/CVE-2024-26680/index.md)","id":"CVE-2024-26680","markdown":"https://insights.sbomify.com/CVE-2024-26680/index.md","name":"CVE-2024-26680","record":{"aliases":["AZL-58728","BELL-CVE-2024-26680","DEBIAN-CVE-2024-26680","GHSA-xhhv-7xxm-fwgf","ROOT-OS-DEBIAN-11-CVE-2024-26680","UBUNTU-CVE-2024-26680"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"low_privilege","summary":"A mismatch in DMA memory mapping sizes in the Atlantic network driver can lead to a use-after-free condition, potentially causing a system crash.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: atlantic: Fix DMA mapping for PTP hwts ring\n\nFunction aq_ring_hwts_rx_alloc() maps extra AQ_CFG_RXDS_DEF bytes\nfor PTP HWTS ring but then generic aq_ring_free() does not take this\ninto account.\nCreate and use a specific function to free HWTS ring to fix this\nissue.\n\nTrace:\n[  215.351607] ------------[ cut here ]------------\n[  215.351612] DMA-API: atlantic 0000:4b:00.0: device driver frees DMA memory with different size [device address=0x00000000fbdd0000] [map size=34816 bytes] [unmap size=32768 bytes]\n[  215.351635] WARNING: CPU: 33 PID: 10759 at kernel/dma/debug.c:988 check_unmap+0xa6f/0x2360\n...\n[  215.581176] Call Trace:\n[  215.583632]  \u003cTASK\u003e\n[  215.585745]  ?
