Specifically:\n\n- in_ie[cnt + 1] is read without checking cnt + 1 < in_len\n- memcmp(&in_ie[cnt + 2], ...) accesses cnt + 2 without bounds check\n- in_ie[cnt + 1] is used as length without verifying payload fits\n\nAdd bounds checks at the top of the loop body to break early if fewer\nthan 2 bytes remain for the IE header, or if the declared payload\nextends past the end of the buffer. Also require at least 4 bytes of\npayload before comparing the WPS OUI.\n\n## Affected\n\n- `Linux >= 554c0a3abf216c991c5ebddcdb2c08689ecd290b < c670efe69ec8a3360bfa596436f0250a3bf15d42`\n- `Linux >= 554c0a3abf216c991c5ebddcdb2c08689ecd290b < 23b630e334f7e8f76bb22a18aca350da995af905`\n- `Linux >= 554c0a3abf216c991c5ebddcdb2c08689ecd290b < b9d9a4cd2e59df7281992a076464d2536e80c674`\n- `Linux >= 554c0a3abf216c991c5ebddcdb2c08689ecd290b < 630fdca3f2437fee3ffd437c4b646ccf84c7be87`\n- `Linux >= 554c0a3abf216c991c5ebddcdb2c08689ecd290b < 875479f18835ac11e21a83e88f3d4dc7ccdcd0c4`\n- `Linux >= 554c0a3abf216c991c5ebddcdb2c08689ecd290b < 23c31f107b4f8f420a754a45d12599bdb78f9bb8`\n- `Linux >= 554c0a3abf216c991c5ebddcdb2c08689ecd290b < 0e95ff792ae0aa6fbad9455943e9e1e4062670e9`\n- `Linux 4.12`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
