CVE-2023-54274

In the Linux kernel, the following vulnerability has been resolved: RDMA/srpt: Add a check for valid 'madagent' pointer When unregistering MAD agent, srpt module has a non-null check for 'madagent' pointer before invoking ibunregistermadagent. This check can pass if 'madagent' variable holds an...

CVE-2023-54274

CVE-2023-54274 affects the Linux kernel RDMA/srpt path. Root cause: during unregistering a MAD agent the code could see a non-null mad_agent that actually held an error value, allowing a NULL dereference in a short race window when srpt_add_one() and srpt_remove_one() run concurrently (e.g., RoCE...

Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from a failure to validate the validity of the madagent pointer in RDMA/srpt, which could result in a null pointe...

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

A flaw was addressed in the Linux kernel’s RDMA SRPT SCSI RDMA Protocol Target subsystem. When unregistering a MAD Management Datagram agent, the SRPT module previously performed a non-NULL check on the madagent pointer before invoking ibunregistermadagent. Under rare timing...
