CVE-2024-26647

Summary

CVE-2024-26647 is a vulnerability affecting the Linux kernel that has been addressed. In the function "link_set_dsc_pps_packet()" of the file "drivers/gpu/drm/amd/amdgpu/../display/dc/link/link_dpms.c", a NULL pointer check was missing before dereferencing 'struct display_stream_compressor *dsc'. This issue led to a late dereference of 'dsc' in the line DC_LOGGER_INIT(dsc->ctx->logger), potentially resulting in undefined behavior or application crashes. The vulnerability has been rectified to include the necessary pointer validation before dereferencing.
