CVE-2026-99257 Nov 3, 2026 Source: Vendor
In the Linux kernel, the following vulnerability has been resolved:
gpio: shared: gracefully handle no-device lookup of shared GPIOs
We use platform lookup tables for shared GPIOs. This mechanism needs a
struct device to work so fwnode-based lookup with no device associated
currently causes a NULL-pointer deference.
Adding this functionality will require a larger rework and it has never
worked anyway so add a check that allows the kernel to gracefully handle
this situation with an error ahead
