In the Linux kernel, the following vulnerability has been resolved:
media: saa7164: add ioremap return checks and cleanups
Add checks for ioremap return values in saa7164_dev_setup(). If
ioremap for BAR0 or BAR2 fails, release the already allocated PCI
memory regions, remove the device from the global list, decrement
the device count, and return -ENODEV.
This prevents potential null pointer dereferences and ensures proper
cleanup on memory mapping failures.
