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 Use After Free in the iwl_op_mode_dvm_start process due to improper error handling when iwl_setup_deferred_work fails. An attacker can gain read and write access to freed kernel memory by triggering memory exhaustion during driver probe, potentially leading to control-flow corruption or system crash. This is only exploitable if a local user can induce memory exhaustion at the precise moment the driver probe occurs.
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
