CVE-2023-54251

In the Linux kernel, the following vulnerability has been resolved: net/sched: taprio: Limit TCATAPRIOATTRSCHEDCYCLETIME to INTMAX. syzkaller found zero division error 0 in divs64rem called from getcycletimeelapsed, where sched-cycletime is the divisor. We have tests in parsetaprioschedule so tha...

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...

Linux Distros Unpatched Vulnerability : CVE-2023-54251

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - net/sched: taprio: Limit TCATAPRIOATTRSCHEDCYCLETIME to INTMAX. syzkaller found zero division error 0 in divs64rem called from getcycletimeelapsed, where...

kernel: net/sched: taprio: Limit TCA_TAPRIO_ATTR_SCHED_CYCLE_TIME to INT_MAX

A flaw was addressed in the Linux kernel’s traffic scheduling TAPRIO subsystem. The code that handles the TCATAPRIOATTRSCHEDCYCLETIME 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...
