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-2026-23207 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-2026-23207/ (Markdown: https://insights.sbomify.com/CVE-2026-23207/index.md)","id":"CVE-2026-23207","markdown":"https://insights.sbomify.com/CVE-2026-23207/index.md","name":"CVE-2026-23207","record":{"aliases":["AZL-80106","BELL-CVE-2026-23207","DEBIAN-CVE-2026-23207","GHSA-5xf5-gq7p-jfx7","ROOT-OS-DEBIAN-12-CVE-2026-23207","ROOT-OS-DEBIAN-13-CVE-2026-23207","ROOT-OS-UBUNTU-2204-CVE-2026-23207","ROOT-OS-UBUNTU-2404-CVE-2026-23207","UBUNTU-CVE-2026-23207"],"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 race condition in the Tegra210 QSPI driver allows a NULL pointer dereference, leading to a kernel crash and denial of service.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":4.7,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"},{"id":"CWE-362","name":"Concurrent Execution using Shared Resource with Improper Synchronization"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nspi: tegra210-quad: Protect curr_xfer check in IRQ handler\n\nNow that all other accesses to curr_xfer are done under the lock,\nprotect the curr_xfer NULL check in tegra_qspi_isr_thread() with the\nspinlock.
