Overview

CVE-2026-23071 is a medium-severity vulnerability. It was published on February 4, 2026 and has a CVSS 3.1 base score of 4.7 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 4.7, rated MEDIUM. 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:

regmap: Fix race condition in hwspinlock irqsave routine

Previously, the address of the shared member '&map->spinlock_flags' was

passed directly to 'hwspin_lock_timeout_irqsave'. This creates a race

condition where multiple contexts contending for the lock could overwrite

the shared flags variable, potentially corrupting the state for the

current lock owner.

Fix this by using a local stack variable 'flags' to store the IRQ state

temporarily.

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.
