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 Uncontrolled Resource Consumption due to inefficient handling in the cleanup_offline_cgwb process. An attacker can cause significant CPU resource exhaustion and system unresponsiveness by triggering scenarios where a large number of inodes are attached to a dying writeback structure, leading to prolonged soft lockups.
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
