CVE-2023-54274
Estado: AplazadaSin puntuar—
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
