漏洞简述：
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 topcie->gpio_id_reset size (MAX_PCI_SLOTS) which is correct and would leadto an overflow.Thus, fix condition to pcie->num_slots + 1 >= MAX_PCI_SLOTS and movepcie->num_slots increment below the if-statement to avoid out-of-boundsarray access.Found by Linux Verification Center (linuxtesting.org) with SVACE.[kwilczynski: commit log]

CVE-2024-47751

影响性分析说明：
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.
