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.

Impact

The kernel driver for the admv1013 IIO device performs a string comparison on a pointer that may not be initialized. When device_property_read_string() fails, the pointer remains unset and the code falls through to a strcmp call, resulting in a NULL or garbage pointer dereference and a kernel fault that brings the system down.

Affected Systems

All Linux kernels that include the admv1013 driver are potentially vulnerable. The product identifier lists the Linux kernel generically, and no specific version range is provided. Patches referenced in the advisory are recent, so any kernel that has not incorporated these fixes—whether from newer releases or custom builds—may still contain the flaw.

Risk and Exploitability

The flaw leads to denial of service through a kernel crash. Local access to the admv1013 device is required to trigger the fault, as the issue arises during a device property read operation. The EPSS score is not available, and the vulnerability is not listed in CISA's KEV catalog. Because the fault is a straightforward pointer dereference in privileged kernel code, the risk of exploitation is considered moderate to high when an attacker can interact with the device. The likely attack vector is local interaction with the admv1013 driver, inferred from the description of the fault being triggered during a property read. No public exploitation kit has been reported.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Apply the backported patch that replaces the unsafe string handling with device_property_match_property_string() and corrects enum handling.
  • Upgrade the Linux kernel to a version that includes the fixed admv1013 driver.
  • If the admv1013 device is not required, disable or unload the driver to eliminate the vulnerable code path.
