Description
In the Linux kernel, the following vulnerability has been resolved:
PCI: kirin: Fix buffer overflow in kirin_pcie_parse_port()
Within kirin_pcie_parse_port(), the pcie->num_slots is compared to
pcie->gpio_id_reset size (MAX_PCI_SLOTS) which is correct and would lead
to an overflow.
Thus, fix condition to pcie->num_slots + 1 >= MAX_PCI_SLOTS and move
pcie->num_slots increment below the if-statement to avoid out-of-bounds
array access.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
