CVE-2026-64584

The CVE concerns the Linux kernel usb gadget f_midi: a work item (midi->work) could dereference a freed f_midi when a pending IN work was not cancelled before f_midi_free() freed the object. The work can be armed by f_midi_complete() and f_midi_in_trigger(), and f_midi_disable() / f_midi_unbin...

EUVD-2026-53771

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: fmidi: cancel pending IN work before freeing the midi object The fmidi driver embeds a work item midi-work whose handler, fmidiinwork, dereferences the enclosing struct fmidi through containerof. This work is armed...

CVE-2026-64327

A flaw was found in the Linux kernel's FunctionFS ffs module, which handles USB gadget functionality. This vulnerability occurs because the endpoint direction epfile-in was not correctly initialized until a USB host connected. Consequently, early operations initiated by userspace programs could...

CVE-2026-64347

A flaw was found in the USB gadget composite driver in the Linux kernel. An issue with an empty check in the USBDTOTG handler can lead to reading from an invalid memory location. This can result in a kernel AddressSanitizer KASAN fault, potentially causing information disclosure or a denial of...

CVE-2026-64454

A flaw was found in the Linux kernel's USB dwc3 driver. A local attacker could trigger a condition where a sleeping function is called from an invalid context during a USB gadget suspend operation. This can lead to system instability or a kernel panic, resulting in a Denial of Service DoS...

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...

The vulnerability of the eem_unwrap() function in the drivers/usb/gadget/function/f_eem.c file of the Linux operating system’s USB gadget driver module allows a hacker to cause a service failure.

The vulnerability of the eemunwrap function in the drivers/usb/gadget/function/feem.c file of the Linux operating system’s USB gadget driver framework is related to improper memory release memory leak. Exploiting this vulnerability could allow a remote attacker to cause service interruptions...
