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...

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...
