CVE-2024-26667: drm/msm/dpu: check for valid hw_pp in dpu_encoder_helper_phys_cleanup
In the Linux kernel, the following vulnerability has been resolved:
drm/msm/dpu: check for valid hwpp in dpuencoderhelperphyscleanup
The commit 8b45a26f2ba9 ("drm/msm/dpu: reserve cdm blocks for writeback in case of YUV output") introduced a smatch warning about another conditional block in dpuencoderhelperphyscleanup() which had assumed hwpp will always be valid which may not necessarily be true.
Lets fix the other conditional block by making sure hwpp is valid before dereferencing it.
