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-2026-53068 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-2026-53068/ (Markdown: https://insights.sbomify.com/CVE-2026-53068/index.md)","id":"CVE-2026-53068","markdown":"https://insights.sbomify.com/CVE-2026-53068/index.md","name":"CVE-2026-53068","record":{"aliases":["BELL-CVE-2026-53068","DEBIAN-CVE-2026-53068","GHSA-5pf3-f93j-64w2","ROOT-OS-DEBIAN-11-CVE-2026-53068","ROOT-OS-DEBIAN-12-CVE-2026-53068","ROOT-OS-UBUNTU-2204-CVE-2026-53068","ROOT-OS-UBUNTU-2404-CVE-2026-53068","UBUNTU-CVE-2026-53068"],"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 DRM","requires_auth":"low_privilege","summary":"An integer overflow in the Linux kernel's Komeda DRM driver allows local attackers to trigger out-of-bounds memory access, potentially leading to code execution or privilege escalation.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/komeda: fix integer overflow in AFBC framebuffer size check\n\nThe AFBC framebuffer size validation calculates the minimum required\nbuffer size by adding the AFBC payload size to the framebuffer offset.\nThis addition is performed without checking for integer overflow.\n\nIf the addition oveflows, the size check may incorrectly succed and\nallow userspace to provide an undersized drm_gem_object, potentially\nleading to out-of-bounds memory access.\n\nAdd usage of check_add_overflow() to safely compute the minimum\nrequired size and reject the framebuffer if an overflow is detected.\nThis makes the AFBC size validation more robust against malformed.\n\nFound by Linux Verification Center (linuxtesting.org) with SVACE.","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/komeda: fix integer overflow in AFBC framebuffer size check","id":"CVE-2026-53068","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"integer_overflow","year":"2026"},"n_packages":0,"n_references":8,"next":{"headline":"net, bpf: fix null-ptr-deref in xdp_master_redirect() for down master","id":"CVE-2026-53069"},"packages":[],"prev":{"headline":"PCI: endpoint: pci-ep-msi: Fix error unwind and prevent double alloc","id":"CVE-2026-53067"},"products":["Linux"],"published":"2026-06-24","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":"2026-08-05","vendors":["Linux"]},"summary":"An integer overflow in the Linux kernel's Komeda DRM driver allows local attackers to trigger out-of-bounds memory access, potentially leading to code execution or privilege escalation.","url":"https://insights.sbomify.com/CVE-2026-53068/"}
