In the Linux kernel, the following vulnerability has been resolved:drm/amd/display: fix a Null pointer dereference vulnerability[Why]A null pointer dereference vulnerability exists in the AMD display driver's(DC module) cleanup function dc_destruct().When display control context (dc->ctx) construction fails(due to memory allocation failure), this pointer remains NULL.During subsequent error handling when dc_destruct() is called,there's no NULL check before dereferencing the perf_trace member(dc->ctx->perf_trace), causing a kernel null pointer dereference crash.[How]Check if dc->ctx is non-NULL before dereferencing.(Updated commit text and removed unnecessary error message)(cherry picked from commit 9dd8e2ba268c636c240a918e0a31e6feaee19404)
