GFP);\n\nIf krealloc() returns NULL, that erases the pointer\nto the still allocated memory, hence leaks this memory.\nInstead, use a temporary variable, check it's not NULL\nand only then assign it to the original pointer:\n\n TMP = krealloc(MEM, SZ, GFP);\n if (!TMP) return;\n MEM = TMP;\n\nWhile on it, use krealloc_array()."}], "affected": [{"product": "Linux", "vendor": "Linux",
