Technical description
In the Linux kernel, the following vulnerability has been resolved:
soc: xilinx: Fix race condition in event registration
The zynqmp_power driver registers handlers for suspend and subsystem
restart events using register_event(). However, the work structures
(zynqmp_pm_init_suspend_work and zynqmp_pm_init_restart_work) used by
these handlers were allocated and initialized after the registration
call.
This created a race window where, if the firmware triggered an event
immediately after registration but before allocation, the callback
(suspend_event_callback or subsystem_restart_event_callback) would
dereference a NULL pointer in work_pending(), leading to a crash.
Fix this by allocating and initializing the work structures before
registering the events.
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-2026-80655?
CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2026-80655 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.
