Upgrade AlmaLinux:8 kernel-rt-debug to version 0:4.18.0-553.5.1.rt7.346.el8_10 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-rt-debug package and not the kernel-rt-debug 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.
