Description
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Add NULL check for function pointer in dcn32_set_output_transfer_func
This commit adds a null check for the set_output_gamma function pointer
in the dcn32_set_output_transfer_func function. Previously,
set_output_gamma was being checked for null, but then it was being
dereferenced without any null check. This could lead to a null pointer
dereference if set_output_gamma is null.
To fix this, we now ensure that set_output_gamma is not null before
dereferencing it. We do this by adding a null check for set_output_gamma
before the call to set_output_gamma.
Affected configurations
• linux linux kernel (< 6.10.14)
• linux linux kernel (>= 6.11 < 6.11.3)
