Описание
In the Linux kernel, the following vulnerability has been resolved:
mmc: mmci: Fix use-after-free in busy-timeout work
ux500_busy_complete() can queue ux500_busy_timeout_work for an R1b command, but mmci_remove() never cancels it. The work can subsequently dereference the devm-allocated mmci_host after it has been released.
Mask the controller interrupts and disable the delayed work during removal. This drains any queued instance and stops an IRQ handler that is still in progress from queueing the work again once it has been disabled.
This issue was found by an in-house static analysis tool.
