CVE-2026-68370 usb: gadget: dummy_hcd: prevent fifo_req reuse during giveback

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 affects the Linux kernel USB gadget dummy_hcd path. A race condition reuses a shared usb_request (fifo_req) before its completion callback finishes, allowing overwriting of the callback pointer and causing a general protection/page fault in dummy_timer. The mitigation adds a fifo_r...

CVE-2026-68367 usb: gadget: f_tcm: synchronize delayed set_alt with teardown

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: ftcm: synchronize delayed setalt with teardown The ftcm setalt path defers endpoint setup to a work item and completes the delayed status response from process context. The delayed work uses ftcm private state and ma...

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...

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 wifi: ath9k: hif_usb: don't dereference hif_dev after re-arming firmware request

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()...
