Description

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

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.

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality none, integrity none, availability high.
