  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\niio: proximity: aw96103: validate firmware data length\n\nThe firmware parser reads a length from the binary header and then uses\nit to walk six-byte register/value entries. A truncated firmware image\ncan make the parser read beyond the copied firmware buffer. A value\nsmaller than the four-byte count field also underflows, producing a very\nlarge length.\n\nRead the little-endian field with get_unaligned_le32(), as previously\nproposed by David Lechner. Validate the header size, reject an\nunderflowed length, ensure the resulting payload is contained in the\nfirmware image, and require it to contain whole register/value entries.",
