GHSA-4qpg-p2c6-564v · Severity: unknown — In the Linux kernel, the following vulnerability has been resolved: pinctrl: pinconf-generic:...
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.
Conclusion & alert: CVE-2026-53307 is rated Low Risk (5/100): low exploitation likelihood (EPSS 0.15%). Mandatory action: Low composite risk—no urgent action required; patch on your normal maintenance cycle and revisit priority if CVSS or EPSS increases.
Risk is dynamic; we continuously reassess and refresh what is shown on this page as upstream context changes.
