CVE-2026-46282 iio: frequency: admv1013: fix NULL pointer dereference on str

What is CVE-2026-46282?

CVE-2026-46282 is a medium-severity vulnerability in Linux kernel, published on 8 Jun 2026. It can only be exploited from the same machine or local network, with no action from the victim.

Official description

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

iio: frequency: admv1013: fix NULL pointer dereference on str

When device_property_read_string() fails, str is left uninitialized but the code falls through to strcmp(str, ...), dereferencing a garbage pointer. Replace manual read/strcmp with device_property_match_property_string() and consolidate the SE mode enums into a single sequential enum, mapping to hardware register values via a switch consistent with other bitfields in the driver.

Several cleanup patches have been applied to this driver recently so this will need a manual backport.

Weakness: CWE-476
