How to fix?

There is no fixed version for RHEL:10 kernel-64k-devel.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-64k-devel package and not the kernel-64k-devel 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:

drm/amdkfd: Unwind debug trap enable on copy_to_user failure

If kfd_dbg_trap_enable() fails while copying runtime_info to userspace, it had already activated the trap, set debug_trap_enabled, taken an extra process reference, and opened the debug event file. Return -EFAULT without unwinding that state, leaving inconsistent trap state and a refcount imbalance that could break later DISABLE/ENABLE.

On copy_to_user failure, deactivate the trap and undo the rest of the enable setup before returning.
