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-2026-74452 in the wild and no public exploit code.\n\nAffected product: Linux. 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-2026-74452/ (Markdown: https://insights.sbomify.com/CVE-2026-74452/index.md)","id":"CVE-2026-74452","markdown":"https://insights.sbomify.com/CVE-2026-74452/index.md","name":"CVE-2026-74452","record":{"aliases":["BELL-CVE-2026-74452","DEBIAN-CVE-2026-74452","GHSA-3jx8-2xh9-q6mh","UBUNTU-CVE-2026-74452"],"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 heap buffer overflow in the Panthor GPU driver allows attackers to execute arbitrary code or escalate privileges via crafted firmware.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"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":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/panthor: reject firmware sections with oversized data\n\nIn panthor_fw_load_section_entry(), the data size to copy is calculated\nwithout validating it against the allocated section_size:\n\n    section-\u003edata.size = hdr.data.end - hdr.data.start;\n\nIf a crafted firmware sets data.size larger than the allocated memory,\nthis could cause a heap buffer overflow in panthor_fw_init_section_mem()\n\n    memcpy(section-\u003emem-\u003ekmap, section-\u003edata.buf, section-\u003edata.size);\n\nAdditionally, if the section-\u003edata.size exceeds the BO size, could this\nmemset underflow the size calculation, leading to a massive out-of-bounds\nzeroing of kernel memory?\n\n    memset(section-\u003emem-\u003ekmap + section-\u003edata.size, 0,\n           panthor_kernel_bo_size(section-\u003emem) - section-\u003edata.size);\n\nReject section entries whose initial data is larger than the section size.","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/panthor: reject firmware sections with oversized data","id":"CVE-2026-74452","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":4,"next":{"headline":"drm/vc4: Zero the tile state data array before each BIN job","id":"CVE-2026-74453"},"packages":[],"prev":{"headline":"drm/panthor: validate firmware interface structure sizes","id":"CVE-2026-74451"},"products":["Linux"],"published":"2026-08-15","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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 heap buffer overflow in the Panthor GPU driver allows attackers to execute arbitrary code or escalate privileges via crafted firmware.","url":"https://insights.sbomify.com/CVE-2026-74452/"}
