CWE-476 NULL Pointer Dereference
Publication date:

Description

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