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-2026-99118/ (Markdown: https://insights.sbomify.com/CVE-2026-99118/index.md)","id":"CVE-2026-99118","markdown":"https://insights.sbomify.com/CVE-2026-99118/index.md","name":"CVE-2026-99118","record":{"aliases":["AZL-111218","BELL-CVE-2026-99118","DEBIAN-CVE-2026-99118","GHSA-v3g3-p6wj-rwgr","UBUNTU-CVE-2026-99118"],"analysis":null,"analysis_generated_by":null,"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\ndrm/i915/dmc: Harden DMC firmware payload parsing\n\nValidate the conversion of the DMC firmware size from dwords to bytes\nusing check_mul_overflow() before calculating the firmware payload size.\n\nReject zero-length payloads and zero MMIO counts in the DMC firmware\nheader so malformed firmware is caught early.
