## Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

> The erdma RDMA driver in the Linux kernel, in versions from 6.0 up to the fixes listed in the affected ranges, is vulnerable. When a hardware destroy command failed, the driver returned early from object destruction, leaking queue buffers, memory translation tables, doorbells and identifiers. The source gives few details on how this is triggered or what an attacker can achieve. Upgrade to a fixed kernel version: 6.1.191 or later in the 6.1 series, 6.6.160 or later in 6.6, 6.12.110 or later in 6.12, or 6.18.52 or later in 6.18.
