CVE-2026-43429

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> USB: usbtmc: Use usb_bulk_msg_killable() with user-specified timeouts<br /> <br /> The usbtmc driver accepts timeout values specified by the user in an<br /> ioctl command, and uses these timeouts for some usb_bulk_msg() calls.<br /> Since the user can specify arbitrarily long timeouts and<br /> usb_bulk_msg() uses unkillable waits, call usb_bulk_msg_killable()<br /> instead to avoid the possibility of the user hanging a kernel thread<br /> indefinitely.
