Linux Kernel Scheduler Vulnerability Affecting Application Dependencies

CVE-2025-38436

What is CVE-2025-38436?

A vulnerability in the Linux kernel's DRM scheduler could result in indefinite hangs for applications that depend on job completion from other terminated entities. Specifically, if one application is killed, its scheduled fence may not be signaled appropriately, preventing dependent applications from freeing up resources and continuing execution. This issue can hinder system performance and responsiveness, making it crucial to apply the necessary fixes that ensure proper signaling during entity termination.
