CVE-2024-26974 is a use-after-free vulnerability in the Linux kernel Intel QuickAssist Technology (QAT) cryptographic accelerator driver during PCI Advanced Error Reporting (AER) recovery. The race occurs when a device restart exceeds the scheduling function's 10-second timeout. The scheduling function then frees the reset-data structure even though the reset worker subsequently uses that structure to signal completion after the restart finishes. The condition manifests as a use-after-free read in the QAT device-reset worker.
