Vulnerability from github – Published: 2024-02-27 21:31 – Updated: 2024-04-10 21:30In the Linux kernel, the following vulnerability has been resolved:
tools/power turbostat: Fix offset overflow issue in index converting
The idx_to_offset() function returns type int (32-bit signed), but MSR_PKG_ENERGY_STAT is u32 and would be interpreted as a negative number. The end result is that it hits the if (offset < 0) check in update_msr_sum() which prevents the timer callback from updating the stat in the background when long durations are used. The similar issue exists in offset_to_idx() and update_msr_sum(). Fix this issue by converting the 'int' to 'off_t' accordingly.
