Linux Kernel PCI/DOE Memory Leak Vulnerability with DEBUG_OBJECTS Configuration

A memory leak vulnerability has been identified in the Linux kernel's PCI/DOE implementation, specifically when the DEBUG_OBJECTS configuration is enabled. The issue arises because the work_struct associated with a completed pci_doe_task is not properly destroyed, leading to the memory leak.

Impact

Exploitation of this vulnerability causes a memory leak, which can lead to increased memory usage and potential exhaustion of system resources over time.

Remediation

Users can upgrade to the latest version of the Linux kernel where this vulnerability has been addressed. Instructions for downloading the patched version are available on the Linux kernel's official website.
