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...

In the Linux kernel, the following vulnerability has been resolved: net/sched: taprio: avoid disabling offload when it was never enabled In an incredibly strange API design decision, qdisc-destroy gets called even if qdisc-init never succeeded, not exclusively since commit 87b60cfacf9f "netsched:...

CVE-2022-48644

A flaw was found in the Linux kernel’s Time-Aware Priority Shaper taprio scheduler. The issue arises because the taprio scheduler attempts to disable hardware offload, even if it was never enabled, due to an unusual API design. This issue can result in improper handling and potential system...

CVE-2022-48644

Summary (CVE-2022-48644): A Linux kernel net/sched taprio offload bug could crash the kernel when disabling offload if flags were left at TAPRIO_FLAGS_INVALID after an error path. The code evaluated FULL_OFFLOAD_IS_ENABLED(q->flags) on an invalid flag value (U32_MAX), causing a crash when tapr...
