In the Linux kernel, the following vulnerability has been resolved: RDMA/core: Reject unregistering netdevs in ibgetethspeed ibdevicegetnetdev intentionally returns a referenced netdevice even when it is unregistering, so matching and cleanup callers can still find the association. The reference...

CVE-2026-98359

A vulnerability exists in the Linux kernel within the RDMA/core component. The function ib_device_get_netdev() returns a referenced net_device even during unregistration to maintain associations. However, ib_get_eth_speed() fails to verify the registration state before invoking its ethtool callba...

CVE-2026-98357

The Linux kernel contains a slab-use-after-free vulnerability within the IB/isert component. The issue arises because isert_send_done() offloads certain completions to isert_comp_wq, but there is no ordering to prevent these work items from running during a teardown. Specifically, isert_wait_conn...
