Overview
CVE-2026-93143 is a known-severity vulnerability. It was published on September 17, 2026.
Technical description
In the Linux kernel, the following vulnerability has been resolved:
staging: media: ipu7: fix pm_runtime refcount leak in ipu7_resume()
ipu7_resume() calls pm_runtime_get_sync() before resuming the device.
If the runtime PM resume fails, the usage count remains incremented, but
the error path returns without dropping the reference.
Use pm_runtime_resume_and_get() instead, which balances the usage count
on failure and avoids the leak. Keep returning 0 on error, as resume
callbacks should not propagate failures to the PM core, matching the
behaviour of the ipu6 driver.
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.

How can CyberStrike help with CVE-2026-93143?
CyberStrike is an open-source, AI-augmented pentesting engine.
