NULL Pointer Dereference in Linux Kernel IIO ADMV1013 Driver

Publication date: 2026-06-08

Last updated on: 2026-06-08

Assigner: kernel.org

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.

Executive Summary

This vulnerability occurs in the Linux kernel's iio frequency admv1013 driver. When the function device_property_read_string() fails, a string variable (str) remains uninitialized. However, the code continues and calls strcmp(str, ...), which dereferences this uninitialized (garbage) pointer, leading to a NULL pointer dereference.

The fix involved replacing the manual read and strcmp operations with device_property_match_property_string(), and consolidating the SE mode enums into a single sequential enum that maps to hardware register values via a switch statement, consistent with other bitfields in the driver.

Impact Analysis

This vulnerability can cause a NULL pointer dereference in the Linux kernel driver, which may lead to a kernel crash or system instability when the affected driver is used. This could result in denial of service or unexpected behavior on systems running the vulnerable driver.
