CVE-2026-45971

The CVE-2026-45971 issue affects the Linux kernel BPF component where allowing large BPF program signature sizes enabled costly allocations (kmalloc_large/vmalloc), risking resource exhaustion and DoS. The vulnerability is described as resolved in the Linux kernel via fixes under the patch set “b...

CVE-2026-45971 bpf: Limit bpf program signature size

In the Linux kernel, the following vulnerability has been resolved: bpf: Limit bpf program signature size Practical BPF signatures are significantly smaller than KMALLOCMAXCACHESIZE Allowing larger sizes opens the door for abuse by passing excessive size values and forcing the kernel into expensi...

CVE-2026-45952 eth: fbnic: Add validation for MTU changes

In the Linux kernel, the following vulnerability has been resolved: eth: fbnic: Add validation for MTU changes Increasing the MTU beyond the HDS threshold causes the hardware to fragment packets across multiple buffers. If a single-buffer XDP program is attached, the driver will drop all multi-fr...
