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-2023-53112 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-2023-53112/ (Markdown: https://insights.sbomify.com/CVE-2023-53112/index.md)","id":"CVE-2023-53112","markdown":"https://insights.sbomify.com/CVE-2023-53112/index.md","name":"CVE-2023-53112","record":{"aliases":["BELL-CVE-2023-53112","DEBIAN-CVE-2023-53112","GHSA-5m24-f4fx-mp4r","UBUNTU-CVE-2023-53112"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"An out-of-bounds array access in the i915 graphics driver can cause a kernel crash, requiring a patch to fix.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.1,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/i915/sseu: fix max_subslices array-index-out-of-bounds access\n\nIt seems that commit bc3c5e0809ae (\"drm/i915/sseu: Don't try to store EU\nmask internally in UAPI format\") exposed a potential out-of-bounds\naccess, reported by UBSAN as following on a laptop with a gen 11 i915\ncard:\n\n  UBSAN: array-index-out-of-bounds in drivers/gpu/drm/i915/gt/intel_sseu.c:65:27\n  index 6 is out of range for type 'u16 [6]'\n  CPU: 2 PID: 165 Comm: systemd-udevd Not tainted 6.2.0-9-generic #9-Ubuntu\n  Hardware name: Dell Inc.
