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...
