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->pctl_dev->dev, but info->pctl_dev is only initialized
after k230_pinctrl_parse_dt() completes.
At the time of DT parsing, info->pctl_dev is still NULL, leading to
the invalid dereference of info->pctl_dev->dev.
Use the already available device pointer from platform_device
instead of accessing through uninitialized pctl_dev.
