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 : The issue affects the Linux kernel in the usb: gadget: f_fs path, specifically the ffs_dmabuf_transfer() flow. A ffs_dma_fence object is kmalloc’d, then dma_fence_init() creates a second reference via dma_resv_add_fence(), while the first reference is not released, causing a memo...
