In the Linux kernel, the following vulnerability has been resolved:
media: cx23885: add ioremap return check and cleanup
Add a check for the return value of pci_ioremap_bar()
in cx23885_dev_setup().
If ioremap for BAR0 fails, release the already allocated
PCI memory region,
decrement the device count, and return -ENODEV.
This prevents a potential null pointer dereference and
ensures proper cleanup
on memory mapping failure.
