CVE-2025-23148

Local denial of service via unchecked revision allocation

Published May 1, 2025 · Updated May 11, 2026

A NULL pointer dereference in Linux exynos_chipid_probe allows local users to cause denial of service on affected Exynos systems. The probe stores the unchecked result of devm_kasprintf in soc_dev_attr->revision, then passes that pointer into SoC registration. The path requires Samsung Exynos hardware and an allocation failure during driver probing; the issue was found statically, with no demonstrated trigger.
