In the Linux kernel, the following vulnerability has been resolved: RDMA/mlx5: Fix devx subscribe-event unwind NULL dereference… (CVE-2026-74395)CVE-2026-74395 0 A null pointer dereference vulnerability in the Linux kernel's RDMA mlx5 driver was resolved. The flaw occurs in the devx subscribe-event unwind path when eventfd_ctx_fdget() fails, leading to a NULL dereference in uverbs_uobject_put(). The issue stems from improper handling of shared error path fields and reference counting for event subscription entries. The fix enforces correct cleanup by ensuring subscribe_event_xa_dealloc() is called only once per key when the last matching pending entry is removed.
