CVE-2025-37995

Kernel crash via uninitialized completion pointer

Published May 29, 2025 · Updated May 11, 2026

Uninitialized-pointer use in the Linux kernel allows local users to crash the system through a module kobject error path. lookup_or_create_module_kobject() creates an internal module_ktype object without a completion pointer, but module_kobject_release() passes that pointer to complete(). The published assessments require local access; Red Hat rates the path as requiring high privileges, while NVD rates it as low privilege.
