      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet/sched: cake: reject overhead values that underflow length\n\nCAKE accepts signed overhead values and stores them in an s16, but the\nadjusted packet length calculation uses unsigned arithmetic.  A negative\neffective length can therefore wrap to a large value.\n\nSuch configurations make rate accounting depend on integer wraparound\nrather than on the packet size userspace intended to model.  A static\nnetlink lower bound is not enough because packets reaching CAKE can be\nsmaller than any reasonable manual-overhead allowance.\n\nFold the signed overhead adjustment into the existing datapath MPU clamp\nso negative adjusted lengths are clamped before link-layer framing\nadjustments.",
