Description
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.

Weaknesses
Common security weaknesses mapped to this vulnerability.
CWE-190
Integer Overflow or Wraparound
The product performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control.
