Threat Intelligence
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version.

Overview
Affected versions of this package are vulnerable to Improper Input Validation in the hisi_acc_vfio_pci live migration process when the VF device driver is not loaded in the guest operating system. An attacker can cause memory exposure, memory corruption, and denial of service by initiating device data migration, resulting in the device accessing a null address and performing DMA operations against unintended memory addresses, which can halt the accelerator for the host and all virtual machines using the device.
Note: The Linux kernel project assigns a CVE to every bug fix it ships, whether or not the bug has been shown to be exploitable. This advisory was generated from that process and has not been individually assessed for exploitability. See the kernel's CVE process documentation: https://github.com/torvalds/linux/blob/master/Documentation/process/cve.rst
