EUVD-2026-28734

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-2026-43429

In the Linux kernel, the following vulnerability has been resolved: USB: usbtmc: Use usbbulkmsgkillable with user-specified timeouts The usbtmc driver accepts timeout values specified by the user in an ioctl command, and uses these timeouts for some usbbulkmsg calls. Since the user can specify...
