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-2026-98298 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-2026-98298/ (Markdown: https://insights.sbomify.com/CVE-2026-98298/index.md)","id":"CVE-2026-98298","markdown":"https://insights.sbomify.com/CVE-2026-98298/index.md","name":"CVE-2026-98298","record":{"aliases":["AZL-106131","BELL-CVE-2026-98298","DEBIAN-CVE-2026-98298","GHSA-262v-749m-59x9","UBUNTU-CVE-2026-98298"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["data_read","data_modify"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"none","summary":"A bug in the Linux kernel MMP PDMA driver causes out-of-bounds reads and data loss due to incorrect scatterlist length handling, potentially exposing memory or corrupting data.","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\ndmaengine: mmp_pdma: fix wrong sg length in mmp_pdma_prep_slave_sg()\n\nIn mmp_pdma_prep_slave_sg(), for_each_sg() iterates the scatterlist\nputting each entry into 'sg', but the entry length is read from 'sgl'\n(the list head) instead of 'sg' (the current entry):\n\n    for_each_sg(sgl, sg, sg_len, i) {\n        addr = sg_dma_address(sg);\n        avail = sg_dma_len(sgl);   /* should be 'sg' */\n\nConsequently 'avail' is always the length of the first entry.
