CVE-2026-53307

Severity CVSS v4.0:
Pending analysis
Type:
CWE-476 NULL Pointer Dereference
Publication date:

Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> pinctrl: pinconf-generic: Fully validate &amp;#39;pinmux&amp;#39; property<br /> <br /> The pinconf_generic_parse_dt_pinmux() assumes that the &amp;#39;pinmux&amp;#39; property<br /> is not empty when present. This might be not true. With that, the allocator<br /> will give a special value in return and not NULL which lead to the crash<br /> when trying to access that (invalid) memory. Fix that by fully validating<br /> &amp;#39;pinmux&amp;#39; value, including its length.
