CVE-2026-31493

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> RDMA/efa: Fix use of completion ctx after free<br /> <br /> On admin queue completion handling, if the admin command completed with<br /> error we print data from the completion context. The issue is that we<br /> already freed the completion context in polling/interrupts handler which<br /> means we print data from context in an unknown state (it might be<br /> already used again).<br /> Change the admin submission flow so alloc/dealloc of the context will be<br /> symmetric and dealloc will be called after any potential use of the<br /> context.
