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-2026-46006 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-2026-46006/ (Markdown: https://insights.sbomify.com/CVE-2026-46006/index.md)","id":"CVE-2026-46006","markdown":"https://insights.sbomify.com/CVE-2026-46006/index.md","name":"CVE-2026-46006","record":{"aliases":["AZL-88607","BELL-CVE-2026-46006","DEBIAN-CVE-2026-46006","GHSA-66r8-mwch-7x3r","ROOT-OS-DEBIAN-11-CVE-2026-46006","ROOT-OS-DEBIAN-12-CVE-2026-46006","ROOT-OS-UBUNTU-2204-CVE-2026-46006","ROOT-OS-UBUNTU-2404-CVE-2026-46006","UBUNTU-CVE-2026-46006"],"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 driver","requires_auth":"low_privilege","summary":"A u32 integer overflow in the nouveau GPU driver allows bypassing bounds checks, potentially leading to memory corruption and 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":7.8,"severity":"high","source":"cna","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-787","name":"Out-of-bounds Write"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/nouveau: fix u32 overflow in pushbuf reloc bounds check\n\nnouveau_gem_pushbuf_reloc_apply() validates each relocation with\n\n    if (r-\u003ereloc_bo_offset + 4 \u003e nvbo-\u003ebo.base.size)\n\nbut reloc_bo_offset is __u32 (uapi/drm/nouveau_drm.h) and the integer\nliteral 4 promotes to unsigned int, so the addition is performed in 32\nbits and wraps before the comparison against the size_t bo size.\n\nCast to u64 so the addition happens in 64-bit arithmetic.\n\n[ Add Fixes: tag. - Danilo ]","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/nouveau: fix u32 overflow in pushbuf reloc bounds check","id":"CVE-2026-46006","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":"hwmon: (powerz) Avoid cacheline sharing for DMA buffer","id":"CVE-2026-46007"},"packages":[],"prev":{"headline":"xfs: fix a resource leak in xfs_alloc_buftarg()","id":"CVE-2026-46005"},"products":["Linux"],"published":"2026-05-27","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":"A u32 integer overflow in the nouveau GPU driver allows bypassing bounds checks, potentially leading to memory corruption and privilege escalation.","url":"https://insights.sbomify.com/CVE-2026-46006/"}
