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-2026-80887 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-2026-80887/ (Markdown: https://insights.sbomify.com/CVE-2026-80887/index.md)","id":"CVE-2026-80887","markdown":"https://insights.sbomify.com/CVE-2026-80887/index.md","name":"CVE-2026-80887","record":{"aliases":["AZL-99603","BELL-CVE-2026-80887","DEBIAN-CVE-2026-80887","GHSA-377r-p949-gf93","UBUNTU-CVE-2026-80887"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["privilege_escalation","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"low_privilege","summary":"Integer overflow in vmwgfx driver allows bypassing bounds checks, potentially leading to privilege escalation or code execution via crafted shader offsets.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/vmwgfx: use check_add_overflow for shader size+offset bound\n\nvmw_shader_define() validates the user-supplied shader window against\nits backing buffer with\n\n\t(u64)buffer-\u003etbo.base.size \u003c (u64)size + (u64)offset\n\ndrm_vmw_shader_create_arg::offset is __u64 in the uapi; when it is\nnear U64_MAX the unsigned addition wraps and the resulting tiny value\npasses the check.
