This issue was patched in ALSA-2024:3618.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-doc package and not the kernel-doc package as distributed by AlmaLinux. See How to fix? for AlmaLinux:8 relevant fixed versions and status.

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.
