CVE-2026-46176

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> RDMA/mlx5: Fix error path fall-through in mlx5_ib_dev_res_srq_init()<br /> <br /> mlx5_ib_dev_res_srq_init() allocates two SRQs, s0 and s1. When<br /> ib_create_srq() fails for s1, the error branch destroys s0 but falls<br /> through and unconditionally assigns the freed s0 and the ERR_PTR s1 to<br /> devr-&gt;s0 and devr-&gt;s1.<br /> <br /> This leads to several problems: the lock-free fast path checks<br /> "if (devr-&gt;s1) return 0;" and treats the ERR_PTR as already initialised;<br /> users in mlx5_ib_create_qp() dereference the freed SRQ or ERR_PTR via<br /> to_msrq(devr-&gt;s0)-&gt;msrq.srqn; and mlx5_ib_dev_res_cleanup() dereferences<br /> the ERR_PTR and double-frees s0 on teardown.<br /> <br /> Fix by adding the same `goto unlock` in the s1 failure path.
