  "details": "In the Linux kernel, the following vulnerability has been resolved:  pinctrl: canaan: k230: Fix NULL pointer dereference when parsing devicetree  When probing the k230 pinctrl driver, the kernel triggers a NULL pointer dereference. The crash trace showed: [    0.732084] Unable to handle kernel NULL pointer dereference at virtual address 0000000000000068 [    0.740737] ... [    0.776296] epc : k230_pinctrl_probe+0x1be/0x4fc  In k230_pinctrl_parse_functions(), we attempt to retrieve the device pointer via info-\u003epctl_dev-\u003edev, but info-\u003epctl_dev is only initialized after k230_pinctrl_parse_dt() completes.  At the time of DT parsing, info-\u003epctl_dev is still NULL, leading to the invalid dereference of info-\u003epctl_dev-\u003edev.  Use the already available device pointer from platform_device instead of accessing through uninitialized pctl_dev.",
