CVE-2023-54235
Estado: AplazadaSin puntuar—
In the Linux kernel, the following vulnerability has been resolved:
PCI/DOE: Fix destroy_work_on_stack() race
The following debug object splat was observed in testing:
This occurs because destroy_work_on_stack() was called after signaling the completion in the calling thread. This creates a race between destroy_work_on_stack() and the task->work struct going out of scope in pci_doe().
Signal the work complete after destroying the work struct. This is safe because signal_task_complete() is the final thing the work item does and the workqueue code is careful not to access the work struct after.
