In both places the existing guard only checks\nskb->len >= hdrlen + 3, which proves bytes up to hdrlen + 2 but not the\nbyte at hdrlen + 3.\n\nRequire hdrlen + 4 bytes before reading that item in both paths. This is\na local source-boundary check only; it does not change the key index\nsemantics.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/062840bdc9ee06169b3c371bf66711f1d7ec0bf4","tags":[]},{"url":"https://git.kernel.org/stable/c/74ed3669f26803b1761c1f55403062bea44c3466","tags":[]},{"url":"https://git.kernel.org/stable/c/c54b643e9a0936d038921c547736574fd7382cea","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
