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-2023-53780 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-2023-53780/ (Markdown: https://insights.sbomify.com/CVE-2023-53780/index.md)","id":"CVE-2023-53780","markdown":"https://insights.sbomify.com/CVE-2023-53780/index.md","name":"CVE-2023-53780","record":{"aliases":["BELL-CVE-2023-53780","DEBIAN-CVE-2023-53780","GHSA-m676-9m54-m6j5","ROOT-OS-DEBIAN-11-CVE-2023-53780","ROOT-OS-UBUNTU-2204-CVE-2023-53780","UBUNTU-CVE-2023-53780"],"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":"none","summary":"A flaw in the Linux kernel's AMD display driver causes display underflows, potentially leading to system instability or denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"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/amd/display: fix FCLK pstate change underflow\n\n[Why]\nCurrently we set FCLK p-state change\nwatermark calculated based on dummy\np-state latency when UCLK p-state is\nnot supported\n\n[How]\nCalculate FCLK p-state change watermark\nbased on on FCLK pstate change latency\nin case UCLK p-state is not supported","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: fix FCLK pstate change underflow","id":"CVE-2023-53780","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2023"},"n_packages":0,"n_references":3,"next":{"headline":"smc: Fix use-after-free in tcp_write_timer_handler().","id":"CVE-2023-53781"},"packages":[],"prev":{"headline":"This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.","id":"CVE-2023-53779"},"products":["Linux"],"published":"2025-12-09","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-05-11","vendors":["Linux"]},"summary":"A flaw in the Linux kernel's AMD display driver causes display underflows, potentially leading to system instability or denial of service.","url":"https://insights.sbomify.com/CVE-2023-53780/"}
