Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: In net/sched: taprio, the variable TCATAPRIOATTRSCHEDCYCLETIME is limited to INTMAX. syzkaller detected no division errors in the function divs64rem, which is called from getcycletimeelapsed. In this function, schd-cycletime serv...

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...
