What it is

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

can: ucan: fix devres lifetime

USB drivers bind to USB interfaces and any device managed resources

should have their lifetime tied to the interface rather than parent USB

device. This avoids issues like memory leaks when drivers are unbound

without their devices being physically disconnected (e.g. on probe

deferral or configuration changes).

Fix the control message buffer lifetime so that it is released on driver

unbind.
