CVE-2026-43430

The issue CVE-2026-43430 affects the Linux kernel USB driver for yurex. A race condition occurs in the probe path where the bbu field is not initialized before the URB completion handler uses it, creating a window during which descriptor data can be overwritten by concurrent probing. This can lea...

CVE-2026-43430 usb: yurex: fix race in probe

In the Linux kernel, the following vulnerability has been resolved: usb: yurex: fix race in probe The bbu member of the descriptor must be set to the value standing for uninitialized values before the URB whose completion handler sets bbu is submitted. Otherwise there is a window during which...

CVE-2026-43428 USB: core: Limit the length of unkillable synchronous timeouts

In the Linux kernel, the following vulnerability has been resolved: USB: core: Limit the length of unkillable synchronous timeouts The usbcontrolmsg, usbbulkmsg, and usbinterruptmsg APIs in usbcore allow unlimited timeout durations. And since they use uninterruptible waits, this leaves open the...

CVE-2026-43427

The CVE covers a Linux kernel issue in the usb: class: cdc-wdm read path. Due to compiler optimization or CPU out-of-order execution, desc->length could be updated after a memmove, causing wdm_read() to observe a new length and copy_to_user() from uninitialized memory, violating LKMM data race...

CVE-2026-43427

In the Linux kernel, the following vulnerability has been resolved: usb: class: cdc-wdm: fix reordering issue in read code path Quoting the bug report: Due to compiler optimization or CPU out-of-order execution, the desc-length update can be reordered before the memmove. If this happens, wdmread...

CVE-2026-43425

The CVE-2026-43425 issue affects the Linux kernel mdc800 USB image driver. mdC800_device_read() submits a download URB and waits for completion; if a timeout occurs and the device is unresponsive, the URB may remain active. A subsequent read() can resubmit the still-active URB, triggering the ker...
