Title
drm/amd/ras: Fix NULL deref in ras_core_get_utc_second_timestamp()
Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/ras: Fix NULL deref in ras_core_get_utc_second_timestamp()
ras_core_get_utc_second_timestamp() retrieves the current UTC timestamp
(in seconds since the Unix epoch) through a platform-specific RAS system
callback and is used for timestamping RAS error events.
The function checks ras_core in the conditional statement before calling
the sys_fn callback. However, when the condition fails, the function
prints an error message using ras_core->dev.
If ras_core is NULL, this can lead to a potential NULL pointer
dereference when accessing ras_core->dev.
Add an early NULL check for ras_core at the beginning of the function
and return 0 when the pointer is not valid. This prevents the
dereference and makes the control flow clearer.
