The following copy starts after the three-byte header,\nand the cursor advance consumes both that header and the four-byte CRC.\n\nRequire the payload to fit after SR_RX_OVERHEAD before copying it or\nadvancing to the next packet. The loop already ensures that the\nremaining buffer is larger than the overhead, so the subtraction is\nsafe.\n\nThe issue was found by our static-analysis tool.\n\n## Affected\n\n- `Linux >= c9b37458e95629b1d1171457afdcc1bf1eb7881d < 92d88c88390fc62444c00a1a22078f838e03891f`\n- `Linux >= c9b37458e95629b1d1171457afdcc1bf1eb7881d < baf07d5153d3af8f98e65e2d3566bc0d50c4e3ac`\n- `Linux >= c9b37458e95629b1d1171457afdcc1bf1eb7881d < 8488779d9bddbdb33588c9fc2c0657a3da773f61`\n- `Linux >= c9b37458e95629b1d1171457afdcc1bf1eb7881d < e1f5b74edccf4c9b671b6bce4435a98746fe5167`\n- `Linux >= c9b37458e95629b1d1171457afdcc1bf1eb7881d < 9b59b00890c5dea355b4cc8795ab8eeafc044e48`\n- `Linux >= c9b37458e95629b1d1171457afdcc1bf1eb7881d < 6ab6c9d120b30c94579192ef83a581a3dda6d79c`\n- `Linux >= c9b37458e95629b1d1171457afdcc1bf1eb7881d < 05b442709bd5256c6c0e11fe56b9a0cb2455c245`\n- `Linux >= c9b37458e95629b1d1171457afdcc1bf1eb7881d < c06bde80ae7a7b595732f7cabcb92cf08db9d56a`\n- `Linux 3.12`\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":[]}
