CVE-2026-90074

In the Linux kernel , the fq_pie network scheduling qdisc sets its default quantum from psched_mtu() without clamping. A device with an extremely large MTU (e.g. a dummy device with max_mtu == 0 accepting MTU 2147483634) causes psched_mtu() to return 0x80000000, which overflows the signed flow-&g...
