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-2023-52485 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-2023-52485/ (Markdown: https://insights.sbomify.com/CVE-2023-52485/index.md)","id":"CVE-2023-52485","markdown":"https://insights.sbomify.com/CVE-2023-52485/index.md","name":"CVE-2023-52485","record":{"aliases":["AZL-55256","AZL-55279","BELL-CVE-2023-52485","GHSA-69cq-jw85-57p8","ROOT-OS-DEBIAN-11-CVE-2023-52485","ROOT-OS-DEBIAN-12-CVE-2023-52485","ROOT-OS-UBUNTU-2204-CVE-2023-52485","UBUNTU-CVE-2023-52485"],"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 missing power state check in the AMD display driver can cause a system hang when sending commands to the DMCUB, leading to denial of service.","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":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":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amd/display: Wake DMCUB before sending a command\n\n[Why]\nWe can hang in place trying to send commands when the DMCUB isn't\npowered on.\n\n[How]\nFor functions that execute within a DC context or DC lock we can\nwrap the direct calls to dm_execute_dmub_cmd/list with code that\nexits idle power optimizations and reallows once we're done with\nthe command submission on success.\n\nFor DM direct submissions the DM will need to manage the enter/exit\nsequencing manually.\n\nWe cannot invoke a DMCUB command directly within the DM execution\nhelper or we can deadlock.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"drm/amd/display: Wake DMCUB before sending a command","id":"CVE-2023-52485","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"denial_of_service","year":"2023"},"n_packages":0,"n_references":2,"next":{"headline":"drm: Don't unref the same fb many times by mistake due to deadlock handling","id":"CVE-2023-52486"},"packages":[],"prev":{"headline":"iommu/arm-smmu-v3: Fix soft lockup triggered by arm_smmu_mm_invalidate_range","id":"CVE-2023-52484"},"products":["Linux"],"published":"2024-02-29","related":[{"cvss_score":8.8,"headline":"Linux Kernel Out-of-Bounds Write","id":"CVE-2026-53266","kev_date_added":"2026-09-18","published":"2026-06-25"},{"cvss_score":8.8,"headline":"Linux Kernel Improper Input Validation","id":"CVE-2013-6282","kev_date_added":"2022-09-15","published":"2013-11-19"},{"cvss_score":8.4,"headline":"Linux Kernel Heap-Based Buffer Overflow","id":"CVE-2022-0185","kev_date_added":"2024-08-21","published":"2022-02-11"},{"cvss_score":8.4,"headline":"Linux Kernel Privilege Escalation","id":"CVE-2013-2094","kev_date_added":"2022-09-15","published":"2013-05-14"},{"cvss_score":7.8,"headline":"Linux Kernel Unspecified","id":"CVE-2026-53362","kev_date_added":"2026-08-27","published":"2026-07-04"},{"cvss_score":7.8,"headline":"Linux Kernel Missing Initialization of a Variable","id":"CVE-2026-46300","kev_date_added":"2026-10-28","published":"2026-05-23"},{"cvss_score":7.8,"headline":"Linux Kernel Race Condition","id":"CVE-2025-39964","kev_date_added":"2026-09-18","published":"2025-10-13"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-15","vendors":["Linux"]},"summary":"A missing power state check in the AMD display driver can cause a system hang when sending commands to the DMCUB, leading to denial of service.","url":"https://insights.sbomify.com/CVE-2023-52485/"}
