How to fix?

Upgrade SLES:15.6 kernel-syms-azure to version 6.4.0-150600.8.17.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-syms-azure package and not the kernel-syms-azure package as distributed by SLES. See How to fix? for SLES:15.6 relevant fixed versions and status.

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.
