Has anyone recently experienced memory leak or abnormal memory growth on RHEL 8 systems?

I found this Red Hat KB that appears to mention memory leak / OOM behavior for kernel-4.18.0-553.81.1.el8_10 and later:

https://access.redhat.com/solutions/7134408⁠

We are currently running:

OS: RHEL 8.x

Kernel: 4.18.0-553.83.1.el8_10.x86_64

Over the last few weeks, CrowdStrike's Falcon memory usage started continuously increasing.

I’m a security engineer, so getting access to Red Hat internals isn’t easy and debugging this has been frustrating.

I’m trying to understand whether:

1. anyone has seen similar behavior,

2. this is related to the known RHEL kernel issue,

3. or if this could be Falcon + BPF interaction.

Any experience, workaround, or pointers would really help.

Thanks!
