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-2025-39705 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-2025-39705/ (Markdown: https://insights.sbomify.com/CVE-2025-39705/index.md)","id":"CVE-2025-39705","markdown":"https://insights.sbomify.com/CVE-2025-39705/index.md","name":"CVE-2025-39705","record":{"aliases":["AZL-66983","AZL-70792","BELL-CVE-2025-39705","DEBIAN-CVE-2025-39705","GHSA-jw27-2859-7h38","ROOT-OS-DEBIAN-11-CVE-2025-39705","ROOT-OS-DEBIAN-12-CVE-2025-39705","ROOT-OS-DEBIAN-13-CVE-2025-39705","ROOT-OS-UBUNTU-2204-CVE-2025-39705","ROOT-OS-UBUNTU-2404-CVE-2025-39705","UBUNTU-CVE-2025-39705"],"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 AMD display driver allows local attackers to cause a kernel crash and denial of service.","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\ndrm/amd/display: fix a Null pointer dereference vulnerability\n\n[Why]\nA null pointer dereference vulnerability exists in the AMD display driver's\n(DC module) cleanup function dc_destruct().\nWhen display control context (dc-\u003ectx) construction fails\n(due to memory allocation failure), this pointer remains NULL.\nDuring subsequent error handling when dc_destruct() is called,\nthere's no NULL check before dereferencing the perf_trace member\n(dc-\u003ectx-\u003eperf_trace), causing a kernel null pointer dereference crash.\n\n[How]\nCheck if dc-\u003ectx is non-NULL before dereferencing.\n\n(Updated commit text and removed unnecessary error message)\n(cherry picked from commit 9dd8e2ba268c636c240a918e0a31e6feaee19404)","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 a Null pointer dereference vulnerability","id":"CVE-2025-39705","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"null_dereference","year":"2025"},"n_packages":0,"n_references":4,"next":{"headline":"drm/amdkfd: Destroy KFD debugfs after destroy KFD wq","id":"CVE-2025-39706"},"packages":[],"prev":{"headline":"LoongArch: KVM: Fix stack protector issue in send_ipi_data()","id":"CVE-2025-39704"},"products":["Linux"],"published":"2025-09-05","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":"2026-10-21","vendors":["Linux"]},"summary":"A null pointer dereference in the AMD display driver allows local attackers to cause a kernel crash and denial of service.","url":"https://insights.sbomify.com/CVE-2025-39705/"}
