Overview

CVE-2023-54274 is a known-severity vulnerability. It was published on December 30, 2025.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

RDMA/srpt: Add a check for valid 'mad_agent' pointer

When unregistering MAD agent, srpt module has a non-null check

for 'mad_agent' pointer before invoking ib_unregister_mad_agent().

This check can pass if 'mad_agent' variable holds an error value.

The 'mad_agent' can have an error value for a short window when

srpt_add_one() and srpt_remove_one() is executed simultaneously.

In srpt module, added a valid pointer check for 'sport->mad_agent'

before unregistering MAD agent.

This issue can hit when RoCE driver unregisters ib_device
