Consequently, an\nempty PREQ element causes a one-byte read beyond its declared payload.\n\nMove the helper call after both size checks, so the bottom fields are\nonly accessed when they are present.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/3beddbd56946577478fd5e649f556aaaebe15b0a","tags":[]},{"url":"https://git.kernel.org/stable/c/e6031f02269c0f51cf67886d177f02bc300b47cd","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
