Description :In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
pinctrl: canaan: k230: Fix NULL pointer dereference when parsing devicetree<\/p>\n
When probing the k230 pinctrl driver, the kernel triggers a NULL pointer
\ndereference. The crash trace showed:
\n[ 0.732084] Unable to handle kernel NULL pointer dereference at virtual address 0000000000000068
\n[ 0.740737] …
\n[ 0.776296] epc : k230_pinctrl_probe+0x1be\/0x4fc<\/p>\n
In k230_pinctrl_parse_functions(), we attempt to retrieve the device
\npointer via info->pctl_dev->dev, but info->pctl_dev is only initialized
\nafter k230_pinctrl_parse_dt() completes.<\/p>\n
At the time of DT parsing, info->pctl_dev is still NULL, leading to
\nthe invalid dereference of info->pctl_dev->dev.<\/p>\n
Use the already available device pointer from platform_device
\ninstead of accessing through uninitialized pctl_dev.<\/p>\n
Severity: 0.0 | NA<\/p>\n
