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-2026-23323 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-2026-23323/ (Markdown: https://insights.sbomify.com/CVE-2026-23323/index.md)","id":"CVE-2026-23323","markdown":"https://insights.sbomify.com/CVE-2026-23323/index.md","name":"CVE-2026-23323","record":{"aliases":["DEBIAN-CVE-2026-23323","GHSA-xf4v-3mcr-w96x","UBUNTU-CVE-2026-23323"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"low_privilege","summary":"Out-of-bounds memory access in the Apple Silicon SMC hwmon driver allows potential code execution or system crash due to incorrect sensor array assignment.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","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\nhwmon: (macsmc) Fix regressions in Apple Silicon SMC hwmon driver\n\nThe recently added macsmc-hwmon driver contained several critical\nbugs in its sensor population logic and float conversion routines.\n\nSpecifically:\n- The voltage sensor population loop used the wrong prefix (\"volt-\"\n  instead of \"voltage-\") and incorrectly assigned sensors to the\n  temperature sensor array (hwmon-\u003etemp.sensors) instead of the\n  voltage sensor array (hwmon-\u003evolt.sensors).
