CVE-2026-23071

Severity CVSS v4.0:
Pending analysis
Type:
CWE-362 Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')
Publication date:

Last modified:

Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> regmap: Fix race condition in hwspinlock irqsave routine<br /> <br /> Previously, the address of the shared member &amp;#39;&amp;map-&gt;spinlock_flags&amp;#39; was<br /> passed directly to &amp;#39;hwspin_lock_timeout_irqsave&amp;#39;. This creates a race<br /> condition where multiple contexts contending for the lock could overwrite<br /> the shared flags variable, potentially corrupting the state for the<br /> current lock owner.<br /> <br /> Fix this by using a local stack variable &amp;#39;flags&amp;#39; to store the IRQ state<br /> temporarily.
