Summary
In the Linux kernel, the following vulnerability has been resolved:
media: imx-jpeg: fix a bug of accessing array out of bounds
When error occurs in parsing jpeg, the slot isn't acquired yet, it may
be the default value MXC_MAX_SLOTS.
If the driver access the slot using the incorrect slot number, it will
access array out of bounds.
The result is the driver will change num_domains, which follows
slot_data in struct mxc_jpeg_dev.
Then the driver won't detach the pm domain at rmmod, which will lead to
kernel panic when trying to insmod again.
