Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
iio: chemical: scd30: Cleanup initializations and fix sign-extension bug<br />
<br />
Include linux/bitfield.h for FIELD_GET().<br />
<br />
Create new macros for bit manipulation in combination with manual bit<br />
manipulation being replaced with FIELD_GET().<br />
<br />
The current variable declaration and initializations are barely readable<br />
and use comma separations across multiple lines. Refactor the<br />
initializations so that mantissa and exp have separate declarations and<br />
sign gets initialized later.<br />
<br />
In addition (and due to the nature of the cleanup), fix a sign-extension<br />
bug where, float32 would get bitwise anded with ~BIT(31)<br />
(which is 0xFFFFFFFF7FFFFFFF) which corrupted the exponent.
