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...

CVE-2026-64328

CVE-2026-64328 is a DMA fence memory leak in the Linux kernel's USB gadget FunctionFS (f_fs) driver. In ffs_dmabuf_transfer(), the first reference to an ffs_dma_fence object is never released after dma_resv_add_fence() acquires a second reference, causing objects to accumulate without being freed...
