NVD Description

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

bpf: Guard __get_user acesss with access_ok for uprobe_multi data

As reported by sashiko [1] we need to use access_ok to check the user space data bounds before we use __get-user to get it.
