      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nRDMA/mlx5: Fix error path fall-through in mlx5_ib_dev_res_srq_init()\n\nmlx5_ib_dev_res_srq_init() allocates two SRQs, s0 and s1. When\nib_create_srq() fails for s1, the error branch destroys s0 but falls\nthrough and unconditionally assigns the freed s0 and the ERR_PTR s1 to\ndevr->s0 and devr->s1.\n\nThis leads to several problems: the lock-free fast path checks\n\"if (devr->s1) return 0;\" and treats the ERR_PTR as already initialised;\nusers in mlx5_ib_create_qp() dereference the freed SRQ or ERR_PTR via\nto_msrq(devr->s0)->msrq.srqn; and mlx5_ib_dev_res_cleanup() dereferences\nthe ERR_PTR and double-frees s0 on teardown.\n\nFix by adding the same `goto unlock` in the s1 failure path.",
