CVE-2026-64335 Details
Description
In the Linux kernel, the following vulnerability has been resolved: USB: serial: digi_acceleport: fix broken rx after throttle If the port is closed while throttled, the read urb is never resubmitted and the port will not receive any further data until the device is reconnected (or the driver is rebound). Clear the throttle flags and submit the urb if needed when opening the port.
A vulnerability in the Linux kernel's USB serial Digi Acceleport driver can disrupt data reception if a port is closed while throttled. In such cases, the read URB (USB Request Block) is not resubmitted, causing the port to miss further data until the device is reconnected or the driver is rebound. This issue has been addressed by modifying the driver to clear throttle flags and resubmit the URB when the port is opened.
Users can update to the latest version of the Linux kernel where this vulnerability has been fixed. Instructions for downloading the patched kernel can be found on the official Linux kernel website.
