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-2026-53142 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-2026-53142/ (Markdown: https://insights.sbomify.com/CVE-2026-53142/index.md)","id":"CVE-2026-53142","markdown":"https://insights.sbomify.com/CVE-2026-53142/index.md","name":"CVE-2026-53142","record":{"aliases":["BELL-CVE-2026-53142","DEBIAN-CVE-2026-53142","GHSA-hx3f-5fww-5hr9","ROOT-OS-UBUNTU-2404-CVE-2026-53142","UBUNTU-CVE-2026-53142"],"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 NULL pointer dereference in the Linux kernel's xe display driver causes a system crash during suspend or shutdown when display hardware is disabled via fuses.","user_interaction":"not_required","vuln_class":"null_dereference"},"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-908","name":"Use of Uninitialized Resource"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/xe/display: fix oops in suspend/shutdown without display\n\nThe xe driver keeps track of whether to probe display, and whether\ndisplay hardware is there, using xe-\u003einfo.probe_display. It gets set to\nfalse if there's no display after intel_display_device_probe(). However,\nthe display may also be disabled via fuses, detected at a later time in\nintel_display_device_info_runtime_init().\n\nIn this case, the xe driver does for_each_intel_crtc() on uninitialized\nmode config in xe_display_flush_cleanup_work(), leading to a NULL\npointer dereference, and generally calls display code with display info\ncleared.\n\nCheck for intel_display_device_present() after\nintel_display_device_info_runtime_init(), and reset\nxe-\u003einfo.probe_display as necessary. Also do unset_display_features()\nfor completeness, although display runtime init has already done\nthat. This will need to be unified across all cases later.\n\nMove intel_display_device_info_runtime_init() call slightly earlier,\nsimilar to i915, to avoid a bunch of unnecessary setup for no display\ncases.\n\nNote #1: The xe driver has no business doing low level display plumbing\nlike for_each_intel_crtc() to begin with.
