Description
In the Linux kernel, the following vulnerability has been resolved:
media: pci: cx23885: Fix the error handling in cx23885_initdev()
When the driver fails to call the dma_set_mask(), the driver will get
the following splat:
[ 55.853884] BUG: KASAN: use-after-free in __process_removed_driver+0x3c/0x240
[ 55.854486] Read of size 8 at addr ffff88810de60408 by task modprobe/590
[ 55.856822] Call Trace:
[ 55.860327] __process_removed_driver+0x3c/0x240
[ 55.861347] bus_for_each_dev+0x102/0x160
[ 55.861681] i2c_del_driver+0x2f/0x50
This is because the driver has initialized the i2c related resources
in cx23885_dev_setup() but not released them in error handling, fix this
bug by modifying the error path that jumps after failing to call the
dma_set_mask().
