CVE-2026-93110

CVE-2026-93110 affects the Linux kernel 's RDMA/core subsystem, specifically the ib_core module. The vulnerability arises because put_gid_ndev() is queued via call_rcu(), but stopping workqueues during module unload does not drain already-queued RCU callbacks. Since synchronize_rcu() does not wai...

CVE-2026-93109

CVE-2026-93109 affects the Linux kernel 's RDMA/mlx5_ib module. The root cause is that devx_free_subscription() can remain queued as an RCU callback after the last DevX event file drops its module reference, or after an auxiliary driver detaches its devices. In either case, mlx5_ib can unload bef...
