CVE-2023-54251

The CVE-2023-54251 issue is in the Linux kernel net/sched/taprio path, where TCA_TAPRIO_ATTR_SCHED_CYCLE_TIME was cast inconsistently (s64 cycle_time vs s32 divisor) leading to a potential divide-by-zero in div_s64_rem() called from get_cycle_time_elapsed(). The fix preserves s64 for cycle_time t...
