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-2026-64245 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-2026-64245/ (Markdown: https://insights.sbomify.com/CVE-2026-64245/index.md)","id":"CVE-2026-64245","markdown":"https://insights.sbomify.com/CVE-2026-64245/index.md","name":"CVE-2026-64245","record":{"aliases":["BELL-CVE-2026-64245","DEBIAN-CVE-2026-64245","GHSA-5hjc-xc74-xxjg","ROOT-OS-UBUNTU-2204-CVE-2026-64245","UBUNTU-CVE-2026-64245"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A use-after-free in the Linux kernel's fbdev modedb allows attackers to potentially execute code or escalate privileges via the fb_find_mode function.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nfbdev: modedb: fix a possible UAF in fb_find_mode()\n\nIf mode_option is NULL, it is assigned from mode_option_buf:\n\n  if (!mode_option) {\n    fb_get_options(NULL, \u0026mode_option_buf);\n    mode_option = mode_option_buf;\n  }\n\nLater, name is assigned from mode_option:\n\n  const char *name = mode_option;\n\nHowever, mode_option_buf is freed before name is no longer used:\n\n  kfree(mode_option_buf);\n\nwhile name is still accessed by:\n\n  if ((name_matches(db[i], name, namelen) ||\n\nSince name aliases mode_option_buf, this may result in a\nuse-after-free.\n\nFix this by extending the lifetime of mode_option_buf until the end of the\nfunction by using scope-based resource management for cleanup.","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":"fbdev: modedb: fix a possible UAF in fb_find_mode()","id":"CVE-2026-64245","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"use_after_free","year":"2026"},"n_packages":0,"n_references":5,"next":{"headline":"power: reset: linkstation-poweroff: fix use-after-free in the linkstation_poweroff_init()","id":"CVE-2026-64246"},"packages":[],"prev":{"headline":"drivers/base/memory: set mem-\u003ealtmap after successful device registration","id":"CVE-2026-64244"},"products":["Linux"],"published":"2026-07-24","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":"2026-08-17","vendors":["Linux"]},"summary":"A use-after-free in the Linux kernel's fbdev modedb allows attackers to potentially execute code or escalate privileges via the fb_find_mode function.","url":"https://insights.sbomify.com/CVE-2026-64245/"}
