How to Fix CVE-2026-89866

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-2026-89866, 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: media: chips-media: wave5: Resume device before setting EOS flag Setting the EOS flag talks to the firmware via send_firmware_command(), which accesses VPU registers. Both the STREAMOFF path (wave5_vpu_dec_job_abort()) and the V4L2_DEC_CMD_STOP path (wave5_vpu_dec_stop()) can run while the device is runtime suspended, so those register accesses hit powered-down hardware and the SoC raises an asynchronous SError, panicking the kernel: SError Interrupt on CPU3, code 0x00000000bf000000 -- SError send_firmware_command+0x2c/0x160 [wave5] wave5_vpu_dec_set_bitstream_flag+0x6c/0x80 [wave5] wave5_vpu_dec_update_bitstream_buffer+0x80/0xec [wave5] wave5_vpu_dec_job_abort+0x44/0xa0 [wave5] v4l2_m2m_cancel_job+0x110/0x19c [v4l2_mem2mem] v4l2_m2m_streamoff+0x24/0x140 [v4l2_mem2mem] Resume the device with pm_runtime_resume_and_get() around the EOS firmware command and release it with pm_runtime_put_autosuspend(), matching the runtime PM handling already done in wave5_vpu_dec_device_run().
