Description OSIDB Bzimport 2026-09-17 19:05:06 UTC
In the Linux kernel, the following vulnerability has been resolved:

bnxt_en: Fix call to hardware monitoring event handler

The first parameter of hwmon_notify_event() is supposed to be the hardware
monitoring device. The bnxt driver calls it with the platform device as
first parameter instead. This API break results in undefined behavior and
may result in a crash.

Pass the hardware monitoring device as parameter instead to fix the
problem.
