How to fix?

There is no fixed version for RHEL:10 kernel-rt-modules.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-rt-modules package and not the kernel-rt-modules package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

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

fs/netfs/read_collect: add to next->prev_donated

If multiple subrequests donate data to the same "next" request (depending on the subrequest completion order), each of them would overwrite the prev_donated field, causing data corruption and a BUG() crash ("Can't donate prior to front").
