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.

CVE-2025-22020 (opens in a new tab)How to fix?

Overview
Affected versions of this package are vulnerable to Use After Free in the rtsx_usb_ms_poll_card process. An attacker can achieve arbitrary code execution and escalate privileges by triggering a use-after-free condition through repeated unbind and reset ioctls on a Realtek USB card reader device. This is only exploitable if the attacker has local access to usbfs and the affected hardware is present.
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
