CVE-2026-93121

A flaw was found in the Linux kernel's USB gadget function filesystem ffs component. Specifically, an issue in the ffsdmabuftransfer function's error handling can lead to undefined behavior. This occurs when a fence object is prematurely deallocated without proper initialization, potentially...

CVE-2026-93121

CVE-2026-93121 affects the Linux kernel in the USB gadget f_fs subsystem. The flaw is in ffs_dmabuf_transfer(): the error paths for endpoint-disabled (ESHUTDOWN ) and request-allocation failure (ENOMEM ) call dma_fence_put() on a fence object that has only been kmalloc'd but not yet initialized w...
