EUVD-2026-55471

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: dummyhcd: prevent fiforeq reuse during giveback dummyhcd embeds a single shared usbrequest dum-fiforeq that the "emulated single-request FIFO" fast-path in dummyqueue reuses for small IN transfers: it copies the...

CVE-2026-68370

CVE-2026-68370 concerns Linux kernel usb gadget dummy_hcd. The vulnerability arose from reusing a single shared usb_request (fifo_req) for small IN transfers in an emulated FIFO path. The code copied the caller’s request into fifo_req and queued it, while completion side actions (dummy_timer/dumm...

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: printer: fix infinite loop in printerread printerread uses the same variable for the requested copy size and the number of bytes actually copied to user space. copytouser returns the number of bytes not copied, so wh...

EUVD-2026-55469

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: fncm: validate datagram bounds in ncmunwrapntb When unpacking host-supplied NTBs, ncmunwrapntb checks datagram length against framemax but does not verify that the datagram fits within the declared block length...

CVE-2026-68368 usb: gadget: f_ncm: validate datagram bounds in ncm_unwrap_ntb()

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: fncm: validate datagram bounds in ncmunwrapntb When unpacking host-supplied NTBs, ncmunwrapntb checks datagram length against framemax but does not verify that the datagram fits within the declared block length...

CVE-2026-68368 usb: gadget: f_ncm: validate datagram bounds in ncm_unwrap_ntb()

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: fncm: validate datagram bounds in ncmunwrapntb When unpacking host-supplied NTBs, ncmunwrapntb checks datagram length against framemax but does not verify that the datagram fits within the declared block length...

CVE-2026-68367

The CVE-2026-68367 entry covers the Linux kernel USB gadget driver f_tcm, where the set_alt path defers endpoint setup to a worker and may complete the delayed status after disconnect or teardown. The vulnerability arises from using private f_tcm state in a delayed_work, creating a race between t...

CVE-2026-68366 usb: gadget: uvc: clamp SEND_RESPONSE length to the response buffer

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: uvc: clamp SENDRESPONSE length to the response buffer uvcsendresponse builds the UVC control response from a user-supplied struct uvcrequestdata: req-length = mintunsigned int, uvc-eventlength, data-length;...

CVE-2026-68366

The CVE concerns the Linux kernel USB gadget UVC path. In uvc_send_response, the code builds a control response from a user-supplied uvc_request_data and sets req->length = min(uvc->event_length, data->length). The operation then memcpy(req->buf, data->data, req->length). Since ...

CVE-2026-68365 USB: serial: io_edgeport: cap received transmit credits

In the Linux kernel, the following vulnerability has been resolved: USB: serial: ioedgeport: cap received transmit credits The interrupt-status packet reports transmit credits returned by the device. edgeinterruptcallback adds the 16-bit value to txCredits without checking maxTxCredits. edgewrite...

CVE-2026-68365

The CVE concerns the Linux kernel USB serial driver for io_edgeport. The vulnerability arises because edge_interrupt_callback() adds a 16-bit transmit-credits value to txCredits without enforcing maxTxCredits. edge_write() then uses (txCredits − software FIFO count) as the data that fits, and sin...

EUVD-2026-55464

In the Linux kernel, the following vulnerability has been resolved: wifi: ath9k: hifusb: don't dereference hifdev after re-arming firmware request ath9khifrequestfirmware re-arms an asynchronous firmware load via requestfirmwarenowait, passing hifdev as the completion context, and then still...

CVE-2026-68363

The CVE affects the Linux kernel ath9k wireless driver (ath9k_htc) in the hif_usb path. The vulnerability arises when an asynchronous firmware load is re-armed via request_firmware_nowait(), which passes hif_dev as the completion context and later dereferences hif_dev in a post-request dev_info()...

EUVD-2026-55445

In the Linux kernel, the following vulnerability has been resolved: usb: atm: ueagle-atm: reject descriptors that confuse probe and disconnect ueaprobe distinguishes a pre-firmware device from a post-firmware one using the USB id UEAISPREFIRM, and stores a different object as the interface data i...

CVE-2026-68344

The CVE concerns the Linux kernel USB ATM driver (ueagle-atm). A pre-/post-firmware descriptor mismatch in uea_probe() vs uea_disconnect() allows a crafted device to cause an out-of-bounds access when tracing interface data, due to incorrect handling of interface data (struct completion vs struct...

EUVD-2026-55332

In the Linux kernel, the following vulnerability has been resolved: media: airspy: Return queued buffers on startstreaming failure The vb2 framework hands buffers to the driver via bufqueue before calling startstreaming. If startstreaming returns an error without first returning those buffers via...

CVE-2026-68222

The CVE concerns the Linux kernel media: msi2500 driver. It fixes a leak of vb2 buffers when start_streaming() errors occur before buffers are returned with vb2_buffer_done(). The root cause was five error paths in msi2500_start_streaming() that overwrote or skipped error handling, causing queued...

CVE-2026-68195 wifi: mt76: mt7615: drop TXRX_NOTIFY on non-mmio buses

In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7615: drop TXRXNOTIFY on non-mmio buses PKTTYPETXRXNOTIFY is an mmio-only event, but mt7615rxcheck and mt7615queuerxskb dispatch it to mt7615mactxfree on every bus. mt7615mactxfree cleans the DMA tx queues with...
