CVE-2026-53307

MediumCVSS 5.5/10Last modified Jul 6, 2026

Description

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

pinctrl: pinconf-generic: Fully validate 'pinmux' property

The pinconf_generic_parse_dt_pinmux() assumes that the 'pinmux' property is not empty when present. This might be not true. With that, the allocator will give a special value in return and not NULL which lead to the crash when trying to access that (invalid) memory. Fix that by fully validating 'pinmux' value, including its length.
