CVE-2025-38637

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> net_sched: skbprio: Remove overly strict queue assertions<br /> <br /> In the current implementation, skbprio enqueue/dequeue contains an assertion<br /> that fails under certain conditions when SKBPRIO is used as a child qdisc under<br /> TBF with specific parameters. The failure occurs because TBF sometimes peeks at<br /> packets in the child qdisc without actually dequeuing them when tokens are<br /> unavailable.<br /> <br /> This peek operation creates a discrepancy between the parent and child qdisc<br /> queue length counters. When TBF later receives a high-priority packet,<br /> SKBPRIO&amp;#39;s queue length may show a different value than what&amp;#39;s reflected in its<br /> internal priority queue tracking, triggering the assertion.<br /> <br /> The fix removes this overly strict assertions in SKBPRIO, they are not<br /> necessary at all.
