CVE-2024-49911
Summary
A bug in the AMD graphics driver for Linux has been fixed, which could have caused the system to crash if a certain function was not properly set. This fix ensures that the system checks for the function before using it, preventing potential crashes. Linux users with AMD graphics should update their kernel to take advantage of this fix.

Original description
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Add NULL check for function pointer in dcn20_set_output_transfer_func
This commit adds a null check for the set_output_gamma function pointer
in the dcn20_set_output_transfer_func function. Previously,
set_output_gamma was being checked for null at line 1030, but then it
was being dereferenced without any null check at line 1048. This could
potentially lead to a null pointer dereference error 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 at line 1048.
