A flaw was found in the Linux kernel. A race condition in the timekeeping subsystem, specifically within the __do_adjtimex() function, can occur when the auxiliary clock is handled. This allows uninitialized stack data to be used in calculations and subsequently leaked to userspace, leading to information disclosure.
