Overview

CVE-2025-37845 is a high-severity vulnerability. It was published on May 9, 2025 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

tracing: fprobe events: Fix possible UAF on modules

Commit ac91052f0ae5 ("tracing: tprobe-events: Fix leakage of module

refcount") moved try_module_get() from __find_tracepoint_module_cb()

to find_tracepoint() caller, but that introduced a possible UAF

because the module can be unloaded before try_module_get(). In this

case, the module object should be freed too. Thus, try_module_get()

does not only fail but may access to the freed object.

To avoid that, try_module_get() in __find_tracepoint_module_cb()

again.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
