CVE-2026-64328

A flaw was found in the Linux kernel's USB gadget subsystem. Specifically, a DMA Direct Memory Access fence leak exists in the ffs module's ffsdmabuftransfer function. This issue causes ffsdmafence objects to be allocated without their initial reference being properly released. Repeated...

CVE-2026-64328 usb: gadget: f_fs: Fix DMA fence leak

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: ffs: Fix DMA fence leak In ffsdmabuftransfer, a ffsdmafence object is kmalloc'd, with the underlying dmafence later initialized by dmafenceinit, which sets its kref counter to 1. Then, dmaresvaddfence gets a second...
