Vulnerability from github – Published: 2026-05-08 15:31 – Updated: 2026-05-20 18:31

Details

In the Linux kernel, the following vulnerability has been resolved:

USB: usbtmc: Use usb_bulk_msg_killable() with user-specified timeouts

The usbtmc driver accepts timeout values specified by the user in an ioctl command, and uses these timeouts for some usb_bulk_msg() calls. Since the user can specify arbitrarily long timeouts and usb_bulk_msg() uses unkillable waits, call usb_bulk_msg_killable() instead to avoid the possibility of the user hanging a kernel thread indefinitely.

Severity

5.5 (Medium)
