CVE-2026-98658

In the Linux kernel, the following vulnerability has been resolved:

iio: proximity: aw96103: validate firmware data length

The firmware parser reads a length from the binary header and then uses it to walk six-byte register/value entries. A truncated firmware image can make the parser read beyond the copied firmware buffer. A value smaller than the four-byte count field also underflows, producing a very large length.

Read the little-endian field with get unaligned le32(), as previously proposed by David Lechner. Validate the header size, reject an underflowed length, ensure the resulting payload is contained in the firmware image, and require it to contain whole register/value entries.
