In the Linux kernel, the following vulnerability has been resolved: RDMA/iwcm: Fix workqueue list corruption by removing worklist The commit e1168f0 "RDMA/iwcm: Simplify cmeventhandler" changed the work submission logic to unconditionally call queuework with the expectation that queuework would...

CVE-2026-45898

The CVE-2026-45898 issue affects the Linux kernel’s RDMA/iwcm component, where flawed work submission logic could cause queue_work() to queue items that are still live, enabling a work item to be processed and freed while still on the workqueue and triggering list corruption. The root cause is th...
