A firmware response with\na length field larger than expected overruns the caller buffer and\nreads past the end of the reply allocation.\n\nReplace the dead -ENOMEM check with an active validation that\nreply->length fits within val_len before the memcpy.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/02886c18a340da59df57365f29009e1258bfe333","tags":[]},{"url":"https://git.kernel.org/stable/c/71d140099165de03128c00dd129f1eab21c6a3c4","tags":[]},{"url":"https://git.kernel.org/stable/c/7acb36fd60a3e7b858f12e69a919c3609b281408","tags":[]},{"url":"https://git.kernel.org/stable/c/ce67ebe9d8629776ce38e6995ae72fb903c828db","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
