Vulnerability from cvelistv5
Published

Modified

Severity ?
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: RDMA/srpt: Do not register event handler until srpt device is fully setup Upon rare occasions, KASAN reports a use-after-free Write in srpt_refresh_port(). This seems to be because an event handler is registered before the srpt device is fully setup and a race condition upon error may leave a partially setup event handler in place. Instead, only register the event handler after srpt device initialization is complete.
