NULL Pointer Dereference
Publication date:

Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
drm/amd/display: Add NULL check for function pointer in dcn20_set_output_transfer_func<br />
<br />
This commit adds a null check for the set_output_gamma function pointer<br />
in the dcn20_set_output_transfer_func function. Previously,<br />
set_output_gamma was being checked for null at line 1030, but then it<br />
was being dereferenced without any null check at line 1048. This could<br />
potentially lead to a null pointer dereference error if set_output_gamma<br />
is null.<br />
<br />
To fix this, we now ensure that set_output_gamma is not null before<br />
dereferencing it. We do this by adding a null check for set_output_gamma<br />
before the call to set_output_gamma at line 1048.
