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-2026-74422 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-2026-74422/ (Markdown: https://insights.sbomify.com/CVE-2026-74422/index.md)","id":"CVE-2026-74422","markdown":"https://insights.sbomify.com/CVE-2026-74422/index.md","name":"CVE-2026-74422","record":{"aliases":["DEBIAN-CVE-2026-74422","GHSA-j9hg-prqv-m4rx","UBUNTU-CVE-2026-74422"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"none","summary":"A use-after-free in the Rockchip HDMI driver allows local attackers to cause a system crash or potentially execute code.","user_interaction":"not_required","vuln_class":"use_after_free"},"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\ndrm/rockchip: inno-hdmi: Switch to drmm_kzalloc()\n\nDriver makes use of drmm_encoder_init() to initialize the encoder and\nautomatically handle the cleanup by registering drm_encoder_cleanup()\nwith drmm_add_action().\n\nHowever, the internal structure containing the encoder part gets\nallocated with devm_kzalloc(), which happens while component_bind_all()\nis being called from Rockchip DRM driver.
