kernel: RDMA/mlx4: Fix mis-use of RCU in mlx4_srq_event()

A flaw was found in the Linux kernel's RDMA/mlx4 component. This vulnerability arises from the incorrect use of Read-Copy Update RCU in the mlx4srqevent function. An attacker could potentially trigger an event before the srq object is fully initialized, leading to a system crash. This could resul...

SUSE CVE-2026-46181

In the Linux kernel, the following vulnerability has been resolved: RDMA/mlx4: Fix mis-use of RCU in mlx4srqevent Sashiko points out the radixtree itself is RCU safe, but nothing ever frees the mlx4srq struct with RCU, and it isn't even accessed within the RCU critical section. It also will crash...

CVE-2026-46176

The CVE-2026-46176 issue affects the Linux kernel RDMA mlx5 path (mlx5_ib_dev_res_srq_init): when ib_create_srq() fails for s1, the error path can end up with freed s0 and ERR_PTR s1 assigned to devr->s0/devr->s1, leading to use-after-free/double-free risk in subsequent access. The fix adds...
