CVE-2025-38388

CVSS v3.1

5.5

Medium

VectorAV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description The Linux kernel contained an issue where a mutex was used to protect the notifier hashtable accesses, potentially leading to sleeping within an atomic context. This resulted in kernel warnings during operation. The issue was addressed by replacing the mutex with a read-write lock (rwlock). This change allows concurrent read access while maintaining exclusive write access, preventing potential deadlocks and resolving lockdep warnings related to sleeping in an atomic context.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
