Description
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.
Affected configurations
• linux linux kernel (>= 2.6.32 < 6.1.175)
• linux linux kernel (>= 6.2 < 6.6.140)
• linux linux kernel (>= 6.7 < 6.12.90)
• linux linux kernel (>= 6.13 < 6.18.32)
