What it is

In the Linux kernel, the following vulnerability has been resolved:

parisc: eisa: Fix infinite loop when parsing invalid IRQ value

When an invalid value is passed via the "eisa_irq_edge=" kernel

command line parameter (e.g. "eisa_irq_edge=16,5"), eisa_irq_setup()

prints an error message and continues without advancing the current

position. As a result the same invalid value is parsed again and

again, causing an infinite loop while the kernel boots.

Advance to the next comma-separated entry, or stop parsing when there

is no next entry, before continuing so that the remaining entries are

processed normally.
