How to Fix CVE-2026-89945

To remediate this vulnerability, upgrade all affected Software dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2026-89945, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree

Analyze the terminal output to locate any version of Software in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.

Note: The mvn dependency:tree command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under General Security Weakness. In Software, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

In the Linux kernel, the following vulnerability has been resolved: ASoC: cs35l34: drain threaded IRQ before runtime suspend cs35l34_runtime_suspend() currently switches the codec into regcache_cache_only(true), asserts reset low, and powers the device off without first quiescing the threaded IRQ registered by devm_request_threaded_irq(). That leaves a window where cs35l34_irq_thread() can still run after suspend has removed live hardware access. A running system can reach this during runtime PM while the driver still has critical fault IRQs unmasked. If the threaded handler runs in that window, it reads volatile INT_STATUS_1..4 after cache_only has been enabled, ignores the regmap_read() failures, and can still execute the PROT_RELEASE_CTL release sequence or the BST fault power-down writes. Use disable_irq() before entering cache_only/reset-low/power-off so any in-flight threaded handler is drained and no new IRQ thread can run while the device is suspended. Re-enable the IRQ only after runtime_resume() has restored live register access with regcache_sync(). Since probe only logs request_threaded_irq() failures and keeps going, track whether the IRQ was actually installed before disabling or re-enabling it.
