Description:
In the Linux kernel, the following vulnerability has been resolved: ACPI: LPIT: Avoid u32 multiplication overflow In lpit_update_residency() there is a possibility of overflow in multiplication, if tsc_khz is large enough (> UINT_MAX/1000). Change multiplication to mul_u32_u32(). Found by Linux Verification Center (linuxtesting.org) with SVACE.
