Summary

CVE-2025-38028 is a medium-severity Race Condition (CWE-362) vulnerability in Linux Linux Kernel. Its CVSS base score is 4.7 (Medium).

Operationally, ranked at the 1th 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 SC-4 (Information in Shared System Resources) and SC-39 (Process Isolation) — see the control section below for these in your framework.

Vulnerability Data

In the Linux kernel, the following vulnerability has been resolved: NFS/localio: Fix a race in nfs_local_open_fh() Once the clp->cl_uuid.lock has been dropped, another CPU could come in and free the struct nfsd_file that was just added. To prevent that from…

happening, take the RCU read lock before dropping the spin lock.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly mitigates the race on the shared nfsd_file object by preventing unintended access or freeing after the spinlock is dropped.

prevent

Process isolation limits the blast radius of the concurrent CPU access that frees the RCU-protected structure.

prevent

Memory protection mechanisms can block the invalid dereference of the prematurely freed nfsd_file struct.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require proper synchronization primitives and concurrency testing that prevent race conditions.

detects

Security testing can detect race conditions, but does not prevent them at design or coding time.

prevents

Secure SDLC mandates concurrency controls and synchronization primitives that directly prevent race conditions.

prevents

Application security requirements can specify thread-safety and locking rules, but do not prescribe implementation details.

prevents

Secure architecture principles require proper synchronization and resource isolation, addressing the root cause of CWE-362.

prevents

Secure coding standards explicitly forbid unsafe concurrent access patterns and mandate atomic operations or locks.

none

Change management reduces introduction of concurrency bugs during updates, yet does not address the weakness itself.
