HIGH 7.8

DescriptionNVD

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

mmc: vub300: fix use-after-free on disconnect

The vub300 driver maintains an explicit reference count for the controller and its driver data and the last reference can in theory be dropped after the driver has been unbound.

This specifically means that the controller allocation must not be device managed as that can lead to use-after-free.

Note that the lifetime is currently also incorrectly tied the parent USB device rather than interface, which can lead to memory leaks if the driver is unbound without its device being physically disconnected (e.g. on probe deferral).

Fix both issues by reverting to non-managed allocation of the controller.
