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

Description An interrupt synchronization error exists in the dummy-hcd driver. The emulated synchronize irq() function, which ensures all current handler callbacks have returned, was executing before the emulated interrupt-disable process. This sequence allowed emulated interrupts to occur after the synchronization had run, potentially resulting in a callback handler executing while the gadget driver was being unbound.

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