Description
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Check link_res->hpo_dp_link_enc before using it
[WHAT & HOW]
Functions dp_enable_link_phy and dp_disable_link_phy can pass link_res
without initializing hpo_dp_link_enc and it is necessary to check for
null before dereferencing.
This fixes 2 FORWARD_NULL issues reported by Coverity.
Affected configurations
• linux linux kernel (< 6.6.55)
• linux linux kernel (>= 6.7 < 6.10.14)
• linux linux kernel (>= 6.11 < 6.11.2)
