Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
rtc: tps6594: Fix integer overflow on 32bit systems<br />
<br />
The problem is this multiply in tps6594_rtc_set_offset()<br />
<br />
tmp = offset * TICKS_PER_HOUR;<br />
<br />
The "tmp" variable is an s64 but "offset" is a long in the<br />
(-277774)-277774 range. On 32bit systems a long can hold numbers up to<br />
approximately two billion. The number of TICKS_PER_HOUR is really large,<br />
(32768 * 3600) or roughly a hundred million. When you start multiplying<br />
by a hundred million it doesn&#39;t take long to overflow the two billion<br />
mark.<br />
<br />
Probably the safest way to fix this is to change the type of<br />
TICKS_PER_HOUR to long long because it&#39;s such a large number.
