The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-098733 advisory. In the Linux kernel, the following vulnerability has been resolved: net/sched: schhfsc: fix divide-by-zero in rtscmin m2sm converts a u32 slope to a u64 scaled value...

The vulnerability of the rtsc_min() function in the net/sched/sch_hfsc.c module of the Linux operating system’s network/scheduling subsystem allows a attacker to cause a service failure.

The vulnerability of the rtscmin function in the net/sched/schhfsc.c module of the Linux operating system’s network/scheduling subsystem is related to zero-division errors. Exploiting this vulnerability could allow an attacker to cause a service failure...

CVE-2026-31423

In the Linux kernel, the following vulnerability has been resolved: net/sched: schhfsc: fix divide-by-zero in rtscmin m2sm converts a u32 slope to a u64 scaled value. For large inputs e.g. m1=4000000000, the result can reach 2^32. rtscmin stores the difference of two such u64 values in a u32...
