CVE-2024-57953

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

rtc: tps6594: Fix integer overflow on 32bit systems

The problem is this multiply in tps6594_rtc_set_offset()

tmp = offset * TICKS_PER_HOUR;

The "tmp" variable is an s64 but "offset" is a long in the (-277774)-277774 range. On 32bit systems a long can hold numbers up to approximately two billion. The number of TICKS_PER_HOUR is really large, (32768 * 3600) or roughly a hundred million. When you start multiplying by a hundred million it doesn't take long to overflow the two billion mark.

Probably the safest way to fix this is to change the type of TICKS_PER_HOUR to long long because it's such a large number.
