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-2026-53138 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-2026-53138/ (Markdown: https://insights.sbomify.com/CVE-2026-53138/index.md)","id":"CVE-2026-53138","markdown":"https://insights.sbomify.com/CVE-2026-53138/index.md","name":"CVE-2026-53138","record":{"aliases":["AZL-90597","BELL-CVE-2026-53138","DEBIAN-CVE-2026-53138","GHSA-qc6f-vg59-3945","ROOT-OS-DEBIAN-11-CVE-2026-53138","ROOT-OS-DEBIAN-12-CVE-2026-53138","ROOT-OS-UBUNTU-2204-CVE-2026-53138","ROOT-OS-UBUNTU-2404-CVE-2026-53138","UBUNTU-CVE-2026-53138"],"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":"A malformed VBIOS image causes unbounded loops and out-of-bounds reads in the AMD display driver, leading to system hangs or crashes during probe.","user_interaction":"not_required","vuln_class":"denial_of_service"},"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/amd/display: Bound VBIOS record-chain walk loops\n\n[Why \u0026 How]\nAll record-chain walk loops in bios_parser.c and bios_parser2.c use\nfor(;;) and only terminate on a 0xFF record_type sentinel or zero\nrecord_size. A malformed VBIOS image missing the terminator record\ncauses unbounded iteration at probe time, potentially hundreds of\nthousands of iterations with record_size=1. In the final iterations\nnear the BIOS image boundary, struct casts beyond the 2-byte header\nvalidated by GET_IMAGE can also read out of bounds.\n\nCap all 14 record-chain walk loops to BIOS_MAX_NUM_RECORD (256)\niterations. The atombios.h defines up to 22 distinct record types\nand atomfirmware.h has 13.
