CVE-2023-53206
Estado: AnalizadaMedia (5.5)—
In the Linux kernel, the following vulnerability has been resolved:
hwmon: (pmbus_core) Fix NULL pointer dereference
Pass i2c_client to _pmbus_is_enabled to drop the assumption that a regulator device is passed in.
This will fix the issue of a NULL pointer dereference when called from _pmbus_get_flags.
