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-2026-93180 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-2026-93180/ (Markdown: https://insights.sbomify.com/CVE-2026-93180/index.md)","id":"CVE-2026-93180","markdown":"https://insights.sbomify.com/CVE-2026-93180/index.md","name":"CVE-2026-93180","record":{"aliases":["DEBIAN-CVE-2026-93180","GHSA-246m-rh4q-q7v7","UBUNTU-CVE-2026-93180"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"low_privilege","summary":"A local attacker can trigger a kernel crash via a NULL pointer dereference in the Panthor GPU driver during partial unmapping of evicted buffers.","user_interaction":"not_required","vuln_class":"null_dereference"},"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/panthor: Fix NPD issue on partial unmap of an evicted BO\n\nThis commit fixes the NULL pointer dereference issue that would have\nhappened on the split of GPU mapping due to partial unmap of an evicted\nBO. There is a logic to handle the partial unmap of huge pages when the\nGPU mapping is split.
