A USB device can trigger OOB by advertising the maximum\nnumber of properties.\n\nFix by dropping the redundant `+ i`; num_properties is already the correct\nrunning index, as gud_connector_fill_properties() fills the preceding\nslots.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/2c92af27ad23e2fbc0367b11a9027d36d94ef4b3","tags":[]},{"url":"https://git.kernel.org/stable/c/4153a9e008f2512bd3cf90a319436865847369b9","tags":[]},{"url":"https://git.kernel.org/stable/c/59ced288fcba9e91bd38e61a972ad782c4edb7d0","tags":[]},{"url":"https://git.kernel.org/stable/c/5f5e565410b4987e9663f599f9ab0c350f8338d4","tags":[]},{"url":"https://git.kernel.org/stable/c/7e630edb22088df7aa0d55b02237a71e4c9a523d","tags":[]},{"url":"https://git.kernel.org/stable/c/ea57100955c1c2a525ba1a98c18d9a05b25aeedb","tags":[]},{"url":"https://git.kernel.org/stable/c/ee04903fe6a098160d20dde4fc5af4cb42846735","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
