CVE-2025-68194

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The Linux kernel's imon driver contains issues that can lead to hung tasks due to indefinitely holding a device lock. Specifically, the usb rx callback intf0() function can repeatedly resubmit USB requests upon encountering a -EPROTO error, potentially causing RCU stalls and printk flooding. The driver's error recovery scheme is inadequate, continuously retrying operations instead of giving up. Additionally, issues exist where wait for completion interruptible() in the send packet() function may never return if usb rx callback intf0() is not called, also resulting in a hung task. The fix involves modifying error handling for specific error codes and adding a 10-second timeout to send packet().

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
