Technical description
In the Linux kernel, the following vulnerability has been resolved:
HID: roccat: free buffered reports when destroying device
roccat_report_event() duplicates each report with kmemdup() and stores
the allocation in a circular-buffer slot. The allocation is released only
when that slot is reused.
The device destruction paths free struct roccat_device without releasing
reports still stored in cbuf[]. This makes those allocations unreachable
and leaks up to ROCCAT_CBUF_SIZE report buffers per device.
Add a small destructor that frees every buffered report before freeing the
device, and use it in both paths that can destroy a registered device.
Remediation

How can CyberStrike help with CVE-2026-89627?
CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2026-89627 is actually reachable in your own applications and APIs, then verifies each finding before reporting it. That tells you if the weakness is a real, exploitable risk in your environment or a false positive you can safely deprioritize.
