CVE-2023-52683 is an integer-overflow vulnerability in the Linux kernel ACPI Low Power Idle Table (LPIT) implementation, in lpit_update_residency(). A 32-bit multiplication can overflow when tsc_khz exceeds UINT_MAX/1000. The issue was introduced in Linux kernel 4.15. The upstream correction performs the calculation with mul_u32_u32(), avoiding 32-bit arithmetic overflow.
