Title
net/mlx5e: SHAMPO, Fix invalid WQ linked list unlink
Summary
In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: SHAMPO, Fix invalid WQ linked list unlink When all the strides in a WQE have been consumed, the WQE is unlinked from the WQ linked list (mlx5_wq_ll_pop()). For SHAMPO, it is possible to receive CQEs with 0 consumed strides for the same WQE even after the WQE is fully consumed and unlinked. This triggers an additional unlink for the same wqe which corrupts the linked list. Fix this scenario by accepting 0 sized consumed strides without unlinking the WQE again.

This is the network stack\u0027s receive path, not a syscall or ioctl interface.\nAC:L - The attacker controls the entire traffic pattern (flow count, segment sizes, session-flush triggers, packet rate) that drives SHAMPO coalescing to WQE boundaries, and can sustain it at line rate indefinitely, so the zero-consumed-strides CQE condition is hit repeatedly and reliably. There is no race against an uncontrolled party and no memory-layout precondition for the trigger.\nPR:N - No account, credentials, or authentication of any kind are required \u2014 the corruption happens in the NAPI RX completion path before any socket or protocol authorization layer is consulted. The attacker only needs to send packets that the NIC receives.\nUI:N - Packet processing happens automatically in the driver\u0027s NAPI poll; no administrator or user action is needed once the interface is up and receiving traffic.\nS:U - The corrupted WQ linked list, the underflowed cur_sz counter, and the prematurely released page-pool pages all belong to the host kernel\u0027s own RX ring. No hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - The self-referencing free list and cur_sz underflow cause page-pool pages to be released while still referenced by outstanding hardware descriptors and in-flight skbs, so recycled kernel memory contents can be cross-attributed into packets delivered up the stack to userspace. Memory corruption of this class provides an arbitrary kernel-memory disclosure primitive.\nI:H - After the free-list self-loop stalls head advancement, mlx5e_post_rx_mpwqes() releases pages for which a UMR and RX WQE were already posted, so the NIC keeps DMA\u0027ing fully attacker-controlled packet bytes into freed and reallocated kernel pages \u2014 an arbitrary-content write into reused kernel memory, leverageable for control-flow hijacking. The driver additionally writes through a stale tail_next pointer.\nA:H - The corrupted linked list permanently stalls RQ replenishment and loses network connectivity, and the teardown path (mlx5e_free_rx_descs on link down, MTU change, or RQ recovery) spins re-deallocating the same WQE up to 65535 times, driving page refcount underflow and kernel oops/panic."
