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. Check out the EPSS documentation for more details.

Overview
Affected versions of this package are vulnerable to Use After Free in the hci_unregister_dev process. An attacker can achieve arbitrary code execution, leak kernel memory, or cause a denial of service by racing device teardown with concurrent work re-submission, leading to use-after-free conditions in kernel workqueue structures. This is only exploitable if a local user has access to create and destroy HCI devices and inject HCI frames through device nodes such as /dev/vhci or Bluetooth sockets.
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
