Title
media: pci: cx23885: Fix the error handling in cx23885_initdev()
Summary
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().
