Summary

CVE-2025-37995 is a medium-severity Access of Uninitialized Pointer (CWE-824) vulnerability in Linux Linux Kernel. Its CVSS base score is 5.5 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 7th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SA-15 (Development Process, Standards, and Tools) — see the control section below for these in your framework.

Vulnerability Data

In the Linux kernel, the following vulnerability has been resolved: module: ensure that kobject_put() is safe for module type kobjects In 'lookup_or_create_module_kobject()', an internal kobject is created using 'module_ktype'. So call to 'kobject_put()' on error handling path causes an attempt…

more

to use an uninitialized completion pointer in 'module_kobject_release()'. In this scenario, we just want to release kobject without an extra synchronization required for a regular module unloading process, so adding an extra check whether 'complete()' is actually required makes 'kobject_put()' safe.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation can discover uninitialized pointer accesses through static analysis, dynamic testing, or fuzzing before deployment.

Requiring documented development processes and tools enables use of analyzers or coding standards that identify uninitialized pointer defects.

Security engineering principles can mandate memory-safety practices and language choices that structurally avoid uninitialized pointer use.

prevents

Secure SDLC practices directly prevent uninitialized pointer bugs via coding standards, analysis, and reviews, but eliminating this single weakness only partially fulfills the broader control.

Secure development life cycle mandates practices that reduce uninitialized pointer defects.

degrades

Application security requirements can specify pointer initialization rules.

degrades

Secure architecture principles discourage unsafe pointer handling.

prevents

Secure coding standards directly prohibit use of uninitialized pointers.
