  "details": "In the Linux kernel, the following vulnerability has been resolved:  drm/vc4: fix krealloc() memory leak  Don't just overwrite the original pointer passed to krealloc() with its return value without checking latter:      MEM = krealloc(MEM, SZ, GFP);  If krealloc() returns NULL, that erases the pointer to the still allocated memory, hence leaks this memory. Instead, use a temporary variable, check it's not NULL and only then assign it to the original pointer:      TMP = krealloc(MEM, SZ, GFP);     if (!TMP) return;     MEM = TMP;  While on it, use krealloc_array().",
