CVE-2023-54251

A flaw was addressed in the Linux kernel’s traffic scheduling (TAPRIO) subsystem. The code that handles the TCA_TAPRIO_ATTR_SCHED_CYCLE_TIME attribute did not enforce an upper bound on this value, which could allow excessively large cycle time inputs to be processed. Under certain conditions, this can lead to an integer overflow or wraparound in the scheduling logic. As a result, the kernel may behave unexpectedly and could be made to crash, resulting in a denial of service condition on affected systems.
