Technical description

In the Linux kernel, the following vulnerability has been resolved:

pinctrl: devicetree: fix null pointer dereferencing in pinctrl_dt_to_map

Here is the BUG report by KASAN about null pointer dereference:

BUG: KASAN: null-ptr-deref in strcmp+0x2e/0x50

Read of size 1 at addr 0000000000000000 by task python3/2640

Call Trace:

strcmp

__of_find_property

of_find_property

pinctrl_dt_to_map

kasprintf() would return NULL pointer when kmalloc() fail to allocate.

So directly return ENOMEM, if kasprintf() return NULL pointer.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
