Linux Kernel Vulnerability Affecting RDMA Functionality

CVE-2026-46265

What is CVE-2026-46265?

A vulnerability in the Linux kernel affects the RDMA functionality, particularly during the use of sunrpc. When a reset is triggered, the work queue may improperly handle memory reclamation, leading to potential warnings in the kernel logs. This issue arises specifically with flushing tasks linked to the work queue used for memory reclamation, which can impact the stability of RDMA connections. The flaw is characterized by a trace indicating a failure to ensure that the work queue is designated for memory reclamation, thus necessitating review and remediation.
