Although the\ninitial reply-size check includes a vendor count byte in the fixed layout,\nit does not guarantee that the byte remains after the standard codec array.\n\nIf a controller reply ends immediately after that array, calculating the\nvendor codec array size reads vnd_codecs->num beyond the skb data.  Use\nskb_pull_data() to validate and consume each codec header before using its\ncount in both command variants.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/12a82819b0cada6e304790b1097f8f9006eb6123","tags":[]},{"url":"https://git.kernel.org/stable/c/9c04b9a4d08b95dee901d24b7607c4cbd65fa0a8","tags":[]},{"url":"https://git.kernel.org/stable/c/a6da782fefae611e68a1aa79644065fc8ca5abcd","tags":[]},{"url":"https://git.kernel.org/stable/c/d0795cfd6f655f4de84868a4f4bb41a03f037b3d","tags":[]},{"url":"https://git.kernel.org/stable/c/e4cfd3c4299105237458b27958bd7b0aa4c60795","tags":[]},{"url":"https://git.kernel.org/stable/c/f49a543d76d48f184b34225d9c0e2fc4cbdea8ec","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
