In the Linux kernel, the following vulnerability has been resolved: RDMA/mlx4: Fix mis-use of RCU in mlx4_srq_event() Sashiko points out the radix_tree itself is RCU safe, but nothing ever frees the mlx4_srq struct with RCU, and it isn't even accessed within the RCU critical section. It also will crash if an event is delivered before the srq object is finished initializing. Use the spinlock since it isn't easy to make RCU work, use refcount_inc_not_zero() to protect against partially initialized objects, and order the refcount_set() to be after the srq is fully initialized.

The remote SUSE Linux SLES16 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:22099-1 advisory.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - RDMA/mlx4: Fix mis-use of RCU in mlx4_srq_event() Sashiko points out the radix_tree itself is RCU safe,     but nothing ever frees the mlx4_srq struct with RCU, and it isn't even accessed within the RCU critical     section. It also will crash if an event is delivered before the srq object is finished initializing. Use     the spinlock since it isn't easy to make RCU work, use refcount_inc_not_zero() to protect against     partially initialized objects, and order the refcount_set() to be after the srq is fully initialized.
    (CVE-2026-46181)

Note that Nessus relies on the presence of the package as reported by the vendor.
