CVE-2026-90109

CVE-2026-90109 is a 32-bit integer overflow in the Linux kernel network scheduling subsystem, affecting the gred , bfifo , and plug qdisc enqueue paths. The backlog and packet-length sum is computed in u32 , wrapping at 2³² (4 GiB) . Once the true backlog exceeds this threshold, the wrapped sum a...

CVE-2026-90076

CVE-2026-90076 affects the Linux kernel 's net/sched FQ (Fair Queue) qdisc. In fq_init(), the quantum and initial_quantum values are computed from psched_mtu() without overflow protection. A network device with an extremely large MTU (e.g., a dummy device accepting MTU 2147483634) causes the 32-b...

EUVD-2026-81936

In the Linux kernel, the following vulnerability has been resolved: net/sched: fqcodel: clamp default quantum and mtu fqcodelinit sets q-quantum = pschedmtuqdiscdevsch without clamping. A device with a huge MTU e.g. dummy with maxmtu == 0 accepting MTU 2147483634 makes pschedmtu return 0x80000000...

EUVD-2026-81934

In the Linux kernel, the following vulnerability has been resolved: net/sched: hhf: clamp quantum before hhfchange to avoid overflow hhfinit sets q-quantum = pschedmtuqdiscdevsch with no overflow check. A device with a huge MTU e.g. dummy with maxmtu == 0 accepting MTU 2147483634 makes weight...

kernel: net: qrtr: fix 32-bit integer overflow in qrtr_endpoint_post()

A flaw was found in the Linux kernel's qrtr network component. On 32-bit systems, a 32-bit integer overflow can occur in the qrtrendpointpost function when processing an incoming packet. This overflow can bypass a size validation check, leading to an out-of-bounds write and causing the kernel to...
