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-2023-53168 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-2023-53168/ (Markdown: https://insights.sbomify.com/CVE-2023-53168/index.md)","id":"CVE-2023-53168","markdown":"https://insights.sbomify.com/CVE-2023-53168/index.md","name":"CVE-2023-53168","record":{"aliases":["BELL-CVE-2023-53168","DEBIAN-CVE-2023-53168","GHSA-mhq5-fgp5-4gpg","ROOT-OS-UBUNTU-2204-CVE-2023-53168","UBUNTU-CVE-2023-53168"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel USB driver","requires_auth":"low_privilege","summary":"A timeout misconfiguration in the Linux kernel UCSI ACPI driver can lead to a null pointer dereference and system crash when connecting specific USB-C monitors.","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-476","name":"NULL Pointer Dereference"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nusb: ucsi_acpi: Increase the command completion timeout\n\nCommit 130a96d698d7 (\"usb: typec: ucsi: acpi: Increase command\ncompletion timeout value\") increased the timeout from 5 seconds\nto 60 seconds due to issues related to alternate mode discovery.\n\nAfter the alternate mode discovery switch to polled mode\nthe timeout was reduced, but instead of being set back to\n5 seconds it was reduced to 1 second.\n\nThis is causing problems when using a Lenovo ThinkPad X1 yoga gen7\nconnected over Type-C to a LG 27UL850-W (charging DP over Type-C).\n\nWhen the monitor is already connected at boot the following error\nis logged: \"PPM init failed (-110)\", /sys/class/typec is empty and\non unplugging the NULL pointer deref fixed earlier in this series\nhappens.\n\nWhen the monitor is connected after boot the following error\nis logged instead: \"GET_CONNECTOR_STATUS failed (-110)\".\n\nSetting the timeout back to 5 seconds fixes both cases.","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":"usb: ucsi_acpi: Increase the command completion timeout","id":"CVE-2023-53168","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"null_dereference","year":"2023"},"n_packages":0,"n_references":3,"next":{"headline":"x86/resctrl: Clear staged_config[] before and after it is used","id":"CVE-2023-53169"},"packages":[],"prev":{"headline":"tracing: Fix null pointer dereference in tracing_err_log_open()","id":"CVE-2023-53167"},"products":["Linux"],"published":"2025-09-15","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":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-05-11","vendors":["Linux"]},"summary":"A timeout misconfiguration in the Linux kernel UCSI ACPI driver can lead to a null pointer dereference and system crash when connecting specific USB-C monitors.","url":"https://insights.sbomify.com/CVE-2023-53168/"}
