There is no information about real-world incidents where this issue was exploited.Technical details about exploitation include:
- The
nvmet tcp alloc cmds()function is vulnerable to a NULL pointer dereference. - The
nvmet tcp release queue work()function is where the kernel crash occurs. - The
nvmet tcp install queue()function is involved in the vulnerability. - The
queue->nr cmdsvariable is set to zero to fix the bug in casenvmet tcp alloc cmd()fails.
