  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amd/display: Check null pointers before multiple uses\n\n[WHAT & HOW]\nPoniters, such as stream_enc and dc->bw_vbios, are null checked previously\nin the same function, so Coverity warns \"implies that stream_enc and\ndc->bw_vbios might be null\". They are used multiple times in the\nsubsequent code and need to be checked.\n\nThis fixes 10 FORWARD_NULL issues reported by Coverity.",
