RDMA/srpt: Do not register event handler until srpt device is fully setup

published 2024-04-17 2 y ago modified 2026-10-15 25 d ago also EUVD-2024-24134

cvss: 7.8; version 3.1, CNA
cisa kev: Not listed; not in CISA's catalog
epss: 0.2%; EPSS 0.2% chance of exploitation in 30 days, percentile 15%
public exploits: 0; none known

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

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.
