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.
